Comparative Study of Yaw and Nacelle Tilt Control for a Two-Bladed Downwind W...Yousuf Al Khalifin
Â
The document compares yaw and nacelle tilt control methods for a two-bladed downwind wind turbine using computational structural dynamics analysis. The analysis found that tower top and base shear forces were significantly lower using nacelle tilt control compared to yaw control. However, nacelle tilt control resulted in greater variance in loads, which can increase fatigue damage over time. Further analysis of blade root loads, tower displacements, and blade fatigue is needed to fully assess the feasibility of different control methods for two-bladed downwind wind turbine designs.

Mechanical Analysis of 1st Stage Marine gas turbine Blade paper 3 IJASTAbhijeet Athipet
Â
This document analyzes the failure of a gas turbine blade through mechanical analysis. It summarizes the modeling and finite element analysis of a turbine blade from a 30 MW marine gas turbine engine. The analysis found that the maximum stresses, strains, and temperatures experienced by the blade were within safe limits for the nickel-based superalloy material. In particular, the elongation of the blade tip was not enough to cause rubbing against the casing, indicating the failure was not due to excessive centrifugal forces or temperatures during operation.
In this paper three different cut patterns of brake disc are studied for heat transfer rate. Heat transfer rate increases with number of cuts in the disc. This is because large area is exposed to air which makes more heat transfer through conduction and convection. But increase in number and size of cuts decreases the strength of disc. And analysed thermally in ANSYS for different material and design created in CREO 3.0.

This document summarizes a research paper that presents a non-invasive method for estimating consciousness level using EEG signals. The method uses two electrodes to collect bio-potential signals from the brain, which are then amplified, filtered, and analyzed using fast Fourier transform (FFT) to extract the beta wave frequency range associated with different consciousness levels. Results from drug and alcohol experiments on subjects showed that their brain wave frequencies shifted towards the alpha range when intoxicated, indicating a loss of consciousness. The frequency analysis provides a way to continuously monitor consciousness level.
This document describes a method for efficiently streaming video data over a network by splitting the video frames into non-overlapping blocks. It involves dividing each video frame into blocks, extracting features from each block, and transmitting the blocks separately to allow playback before full transmission. The method is implemented using FPGA and MATLAB tools to split frames, interpolate blocks to original size without blurring, and display the enlarged blocks on a screen for streaming video data. This splitting and interpolation approach allows for higher precision video streaming with reduced data requirements.

This document summarizes a study on connecting a wind farm to an AC load through a rectifier-inverter system and using batteries for energy storage. It discusses how batteries can be charged during periods of high wind by storing surplus power generated, and can discharge to supply the AC load during periods of low wind. MATLAB simulation results are presented showing voltage waveforms with and without batteries connected in parallel to the wind farm. The study highlights the importance of energy storage devices like batteries for ensuring continuous power supply to loads, even during low wind conditions, by charging batteries when wind is high and discharging them when wind is low.
The document proposes a new strategy called Maximum Distance Point Strategy (MDPS) to evaluate spherical form error from points measured by a Coordinate Measuring Machine (CMM). MDPS selects points that are maximally distant from each other to define a candidate sphere, unlike the commonly used Least Squares Method (LSM) which minimizes the sum of squared deviations of all points from the sphere. The results of MDPS are compared to LSM. MDPS is found to provide comparable or better results than LSM, especially when points are not uniformly distributed. The strategy aims to provide a more robust evaluation of spherical form error compared to existing methods.
This document summarizes a study that investigated the elasticity, compressive strength, and shear strength of masonry walls constructed from clay bricks commonly used in East Java, Indonesia. Tests were conducted on brick samples from several areas and mortar mixtures to determine their material properties. The results showed that the properties of the local brick walls differ from descriptions in references from Western countries. Specifically, the strength of the bricks tested was lower than the mortar, unlike Western masonry walls where bricks are stronger than mortar. This suggests existing theories for analyzing masonry strength and failure may not apply and a new approach is needed for Indonesian clay brick walls.

Abstract A rotating turbine blade (bucket) is the component, which converts the kinetic energy of the flowing fluid into mechanical energy. Thus the reliability of these blades is very important for the successful operation of a turbine. Turbine blades experience fluctuating forces when they pass through non-uniform fluid flow from the stationary vanes. The basic design consideration is to avoid or to minimize the dynamic stresses produced by the fluctuating forces. The aim of the project is to estimate the stresses occurring in the packet blade of steam turbine in last stage due to centrifugal forces and steam bending forces. The blade, root and disc are modeled separately in ANSYS package and they are assembled using constrained equations. After giving the constrain equations cyclic symmetric analysis conditions are applied and then static and model analysis are carried out. After that Campbell and safe diagrams are plotted. Index Terms: ANSYS, Campbell diagrams, Cyclic symmetric analysis and Safe diagrams.

Simulation and visualization of the mechanical components have become a predominant phase
during the design and the production stages. Several means are used to improve the design and
to reduce study time. Today, the powerful hardware and the software available on the market
have contributed greatly on the improvement of design, visualization and manufacturing
process of complex parts (turbine blade). In this context, our study is a contribution to the
establishment of a methodology to a CAD modelling and finite element analysis, which allows
us to identify the mechanical behavior of a gas turbine blade. The profile of the blade turbine
model is obtained after regeneration using the CATIA V5R20 software from the retro-design
technique using a FARO-type scanner. The turbine blade is analyzed under a static mechanical
behavior. It has been observed that the maximum stresses and deformations are located in the
vicinity of the root and the upper surface along the turbine blade. On the other hand, the elastic
energy is located at a distance from the root of the turbine blade.

This document summarizes the design and analysis of a multi-stage steam turbine blade and shaft assembly. It describes modeling the turbine blade profiles and patterns as well as the shaft in CAD. Finite element analysis is then used to conduct structural, modal, and thermal analyses on the assembly with different materials to evaluate stresses, displacements, natural frequencies, temperatures and heat transfer. The results indicate that a zinc aluminum alloy with a zirconium coating provides better reliability than other materials due to lower stresses and displacement under thermal and static loads. This improved design can reduce maintenance needs and costs of the steam turbine.
This document analyzes the computational fluid dynamics (CFD) of flue gases over a valve spindle with rotor wings in 2-stroke marine diesel engines. It aims to increase the time between overhauling (TBO) of the engines by modifying the rotor wing design parameters. The study models the spindle-rotor assembly and analyzes temperature, pressure and rotational effects of exhaust gases on the spindle using ANSYS. Modifying the rotor wing inclination angle is found to give more uniform corrosion and increase spindle rotation angle, potentially extending its lifeline. Validation shows the CFD results match published engine data, demonstrating the methodology can help optimize spindle design for reduced maintenance costs.
Modeling and Stress Analysis of Gas Turbine RotorIRJET Journal
Â
This document summarizes a study that analyzed the stress on a gas turbine rotor made from three different materials: aluminum 2618 alloy, titanium Ti-6Al-4V alloy, and nickel MAR-M-247 alloy. A gas turbine rotor model was created in CAD software and imported into FEA software for stress analysis under operating conditions. Stresses, strains, and fatigue life were calculated and compared. The analysis found that while all materials were within safety limits, the nickel MAR-M-247 alloy exhibited the highest fatigue life and is therefore the best material choice for manufacturing gas turbine rotors.
The document discusses past work analyzing stresses in turbine rotors using finite element methods. Several studies are reviewed that used FEM to analyze thermal and mechanical stresses. Transient thermal analysis was found to produce higher stresses than steady state analysis. Maximum stresses occurred in areas with large temperature gradients like the first stage of intermediate pressure casings. Studies analyzed stress variations over time and with changes in governing modes. FEM provided accurate stress results and the ability to optimize turbine design and operation for maximum efficiency and safety. Future work should further explore transient thermal stress analysis using FEM to better understand failure mechanisms.

setup because of the inherent resilience of the blade
or blade assembly. The frequency of these vibrations
depends on the dimensions of the blade or blade
assembly as well as their method of mounting on the
discs. Moving blades in turbine are subjected to time
variable loads in addition to the static loads.

profile is varying from 839.5310C to 735.1620C at
the tip of the blade and the variation is linear along
the path from both inside and outside of the blade.
Considerable changes are not observed from the first

next 36 mm length of blade the temperature is
gradually decreasing and reaching to a temperature of
781.5480C and for another 4 mm length it is almost
constant.., it is observed that the maximum thermal
stress is 1217.and the minimum thermal stress is.the
maximum thermal stress is less than the yield
strength value i.e, 1450.so, based on these values
