ABSTRACT : The problem of the heat transfer in the flow of an incompressible non-Newtonian second-order fluid over an enclosed torsionally oscillating discs in the presence of the magnetic field has been discussed. The obtained differential equations are highly non-linear and contain upto fifth order derivatives of the flow and energy functions. Hence exact or numerical solutions of the differential equations are not possible subject to the given natural boundary conditions; therefore the regular perturbation technique is applied. The flow functions 퐻, 퐺, 퐿 and 푀 are expanded in the powers of the amplitude (taken small) of the oscillations. The behaviour of the temperature distribution at different values of Reynolds number, phase difference, magnetic field and second-order parameters has been studied and shown graphically. The results obtained are compared with those for the infinite torsionally oscillating discs by taking the Reynolds number of out-flow 푅푚 and circulatory flow 푅퐿 equals to zero. Nusselt number at oscillating and stator disc has also been calculated and its behaviour is represented graphically.

Hydrodynamic study of anadjustableheightpacked column operatingIAEME Publication
This document summarizes a study on the hydrodynamic performance of an adjustable height packed column operating on the principle of an air lift pump. The column is packed with glass rings and operates in a closed water loop with air injection at the base. Water flow rates, pressure drop, gas holdup, and efficiency were measured for different air flow rates and submersion depths. The results show that water flow rate increases with air flow rate and submersion depth. Pressure drop follows a second order polynomial relationship with submersion depth. Gas holdup also increases with air flow rate and decreases with water flow rate. The system provides good mixing with low power consumption and could be used for applications involving heat and mass transfer.

Computational Analysis of Turbulent flow heat transfer and pressure loss in D...IRJET Journal
This document discusses computational analysis of turbulent flow, heat transfer, and pressure loss in ducts or pipes with segmental baffles. Segmental baffles are implemented to enhance flow characteristics and thermal performance. Due to the baffles, significant turbulence is generated, increasing friction with the pipe and improving heat transfer but also leading to greater pressure drop. Finite element analysis is conducted using ANSYS Fluent to simulate turbulent flow over a range of Reynolds numbers in smooth and baffled pipes. Results are validated against published experimental and numerical data and show good agreement. Contour plots illustrate increased turbulence and velocity magnitude in baffled pipes compared to smooth pipes.

The nonlinear asymmetric Kelvin-Helmholtz stability of the cylindrical interface between the vapor and liquid phases of a °uid is studied when the phases are enclosed between two cylindri- cal surfaces coaxial with the interface, and when there is mass and heat transfer across the inter- face. The method of multiple time expansion is used for the investigation. The evolution of am- plitude is shown to be governed by a nonlinear ¯rst order di®erential equation. The stability cri- terion is discussed, and the region of stability is displayed graphically. Also investigated in this paper is the viscous linear potential °ow.

Prediction of the liquid film distribution in stratified-dispersed gas-liquid...Marco Bonizzi
The document presents a mathematical model for predicting the distribution of the liquid film in stratified-dispersed gas-liquid flows in horizontal pipelines. The model is based on the assumptions that liquid droplets can only be entrained from the thick liquid layer at the bottom of the pipe, and that smaller droplets deposit via eddy diffusion while larger droplets deposit gravitationally. The model considers the effects of gravitational drainage, droplet deposition and entrainment, and wave spreading on the liquid film distribution. The model is validated against experimental data and CFD simulations. Key findings are that gravitational drainage, droplet effects, and wave spreading determine the film distribution, with wave spreading making the film more uniform at high gas velocities or small pipes.
The Influence of Pore Air Pressure on Slope Stability Under Various Rainfall ...coreconferences
Rainfall is the most important factor to induce landslide, of which rainfall pattern is the main influence parameter. Generally, during the analysis of slope stability under different rainfall patterns, the influence of pore water pressure in saturated zone is mostly considered, while the influence of pore air pressure in unsaturated zone is seldom analyzed from the angle of water-air coupling. Based on the theory of water-air two-phase flow, this paper calculated and simulated the variation of pore air pressure changing with the rainfall time under three typical rainfall patterns (weakened, concentrated and enhanced), and combined the slope stability analysis model of considering pore air pressure to study the influence of pore air pressure on slope stability. The results show that the influence of pore air pressure on slope stability is detrimental under the three rainfall patterns. And the response duration of the pore air pressure is the longest under the weakened rainfall pattern, the concentrated pattern is the second, and the enhanced pattern is the shortest. The influence of pore air pressure on the safety factor of slope stability is the greatest under the weakened rainfall pattern, which can easily lead to the instability of the slope. Thus, we shall take the necessary engineering measures in advance in the event of such rainfall pattern prediction.

One-dimensional compression tests were conducted on soil samples from 8 locations to analyze their compression index before and after yield. The results show that natural soils initially exhibit stiff behavior up to a yield stress value, after which greater compression occurs. When void ratio is plotted against log pressure, the compression behavior of natural soils is located on the left of the normal compression line, similar to overconsolidated soils, and merges with the line at higher stresses. This indicates that the normal compression line represents the state boundary for natural soils. Analysis of compression indices before and after yield can help understand soil settlement behavior under loading.

Living in 21st century in itself reminds all of us the necessity of police and its administration. As more and more we are entering into the modern society and culture, the more we require the services of the so called ‘Khaki Worthy’ men i.e., the police personnel. Whether we talk of Indian police or the other nation’s police, they all have the same recognition as they have in India. But as already mentioned, their services and requirements are different after the like 26th November, 2008 incidents, where they without saving their own lives has sacrificed themselves without any hitch and without caring about their respective family members and wards. In other words, they are like our heroes and mentors who can guide us from the darkness of fear, militancy, corruption and other dark sides of life and so on. Now the question arises, if Gandhi would have been alive today, what would have been his reaction/opinion to the police and its functioning? Would he have some thing different in his mind now what he had been in his mind before the partition or would he be going to start some Satyagraha in the form of some improvement in the functioning of the police administration? Really these questions or rather night mares can come to any one’s mind, when there is too much confusion is prevailing in our minds, when there is too much corruption in the society and when the polices working is also in the questioning because of one or the other case throughout the India. It is matter of great concern that we have to thing over our administration and our practical approach because the police personals are also like us, they are part and parcel of our society and among one of us, so why we all are pin pointing towards them.

Rural entrepreneurship brings an economic value to the rural sector by creating new methods of production, new markets, new products and generate employment opportunities thereby ensuring continuous rural development. Social Entrepreneurship has the direct and primary objective of serving the society along with the earning profits. So, social entrepreneurship is different from the economic entrepreneurship as its basic objective is not to earn profits but for providing innovative solutions to meet the society needs which are not taken care by majority of the entrepreneurs as they are in the business for profit making as a sole objective. So, the Social Entrepreneurs have the huge growth potential particularly in the developing countries like India where we have huge societal disparities in terms of the financial positions of the population. Still 22 percent of the Indian population is below the poverty line and also there is disparity among the rural & urban population in terms of families living under BPL. 25.7 percent of the rural population & 13.7 percent of the urban population is under BPL which clearly shows the disparity of the poor people in the rural and urban areas. The need to develop social entrepreneurship in agriculture is dictated by a large number of social problems. Such problems include low living standards, unemployment, and social tension. The reasons that led to the emergence of the practice of social entrepreneurship are the above factors. The research problem lays upon disclosing the importance of role of social entrepreneurship in rural development of India. The paper the tendencies of social entrepreneurship in India, to present successful examples of such business for providing recommendations how to improve situation in rural areas in terms of social entrepreneurship development. Indian government has made some steps towards development of social enterprises, social entrepreneurship, and social in- novation, but a lot remains to be improved.
OPTIMAL RECONFIGURATION OF POWER DISTRIBUTION RADIAL NETWORK USING HYBRID MET...IAEME Publication
Distribution system is a critical link between the electric power distributor and the consumers. Most of the distribution networks commonly used by the electric utility is the radial distribution network. However in this type of network, it has technical issues such as enormous power losses which affect the quality of the supply. Nowadays, the introduction of Distributed Generation (DG) units in the system help improve and support the voltage profile of the network as well as the performance of the system components through power loss mitigation. In this study network reconfiguration was done using two meta-heuristic algorithms Particle Swarm Optimization and Gravitational Search Algorithm (PSO-GSA) to enhance power quality and voltage profile in the system when simultaneously applied with the DG units. Backward/Forward Sweep Method was used in the load flow analysis and simulated using the MATLAB program. Five cases were considered in the Reconfiguration based on the contribution of DG units. The proposed method was tested using IEEE 33 bus system. Based on the results, there was a voltage profile improvement in the system from 0.9038 p.u. to 0.9594 p.u.. The integration of DG in the network also reduced power losses from 210.98 kW to 69.3963 kW. Simulated results are drawn to show the performance of each case.
APPLICATION OF FRUGAL APPROACH FOR PRODUCTIVITY IMPROVEMENT - A CASE STUDY OF...IAEME Publication
Manufacturing industries have witnessed an outburst in productivity. For productivity improvement manufacturing industries are taking various initiatives by using lean tools and techniques. However, in different manufacturing industries, frugal approach is applied in product design and services as a tool for improvement. Frugal approach contributed to prove less is more and seems indirectly contributing to improve productivity. Hence, there is need to understand status of frugal approach application in manufacturing industries. All manufacturing industries are trying hard and putting continuous efforts for competitive existence. For productivity improvements, manufacturing industries are coming up with different effective and efficient solutions in manufacturing processes and operations. To overcome current challenges, manufacturing industries have started using frugal approach in product design and services. For this study, methodology adopted with both primary and secondary sources of data. For primary source interview and observation technique is used and for secondary source review has done based on available literatures in website, printed magazines, manual etc. An attempt has made for understanding application of frugal approach with the study of manufacturing industry project. Manufacturing industry selected for this project study is Mahindra and Mahindra Ltd. This paper will help researcher to find the connections between the two concepts productivity improvement and frugal approach. This paper will help to understand significance of frugal approach for productivity improvement in manufacturing industry. This will also help to understand current scenario of frugal approach in manufacturing industry. In manufacturing industries various process are involved to deliver the final product. In the process of converting input in to output through manufacturing process productivity plays very critical role. Hence this study will help to evolve status of frugal approach in productivity improvement programme. The notion of frugal can be viewed as an approach towards productivity improvement in manufacturing industries.
A MULTIPLE – CHANNEL QUEUING MODELS ON FUZZY ENVIRONMENTIAEME Publication
In this paper, we investigated a queuing model of fuzzy environment-based a multiple channel queuing model (M/M/C) ( /FCFS) and study its performance under realistic conditions. It applies a nonagonal fuzzy number to analyse the relevant performance of a multiple channel queuing model (M/M/C) ( /FCFS). Based on the sub interval average ranking method for nonagonal fuzzy number, we convert fuzzy number to crisp one. Numerical results reveal that the efficiency of this method. Intuitively, the fuzzy environment adapts well to a multiple channel queuing models (M/M/C) ( /FCFS) are very well.
