Solar and wind energy are important renewable energy sources. Solar energy harnesses the sun's radiant light and heat, with the amount of solar energy received by the Earth being twice as much as the total energy produced from non-renewable sources. Wind energy uses wind turbines to convert the kinetic energy of wind into mechanical or electrical energy. Both solar and wind energy have advantages such as being clean, abundant sources that do not produce pollution, but also have disadvantages like high upfront costs and unreliable availability depending on sunlight or wind conditions.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

6. INTRODUCTION
Winds are horizontal movement of AIR from an area of HIGH
pressure(H) to an area of low pressure(L).
Wind energy is a kinetic energy associated with movement
of large masses of air.
It is clean, cheap, and eco-friendly renewable source.
Wind energy is utilized as mechanical energy with the help
of a wind turbine.
Moderate to high-speed winds, typically from 5m/s to about
25m/s are considered favorable for most wind turbines.
The electric power generation through wind was first
proposed in Denmark in 1890
7. WHAT IS THE
WIND TURBINES
?
A wind turbine is a rotating machine which converts the
kinetic energy in wind into mechanical energy.The
mechanical energy can be converted into electrical
energy, or it can be used to pump water or grind
crops. If it is used to make electricity, it can be called
a wind turbine, but if it is used to grind or pump, it is
called a windmill.
8. Advantage
of Wind
Turbine.
1.Wind energy is friendly to the surrounding
environment, as no fossil fuels are burnt to generate
electricity form wind energy.
2.Wind turbines take up less space than the average
power station.
3. Newer technologies are making the extraction of wind
energy much more efficient.
4.Wind turbines are a great resource to generate energy
in remote locations, such as mountain communities and
remote countryside.
5.When combined with solar electricity, this energy
source is great for developed and developing countries to
provide a steady, reliable supply of electricity.
6. Birds face many hazards but wind turbines only cause
0.01% of bird fatalities
9. Disadvantage
of Wind
Turbine
1.The main disadvantage regarding wind power is down to
the winds unreliability factor.
2.Wind turbines generally produce allot less electricity than
the average fossil fuelled power station.
3.Wind turbine construction can be very expensive and costly
to surrounding wildlife during the build process.
4.The noise pollution from commercial wind turbines is
sometimes similar to a small jet engine.
