PROJECT/DISSERTATION (SUPERVISED) REPORT
Research done by my undergraduate and graduate students under my supervision is briefly discussed below. In case you find it interesting and want to extend the work get in touch with me along with your idea.
AERODYNAMIC & STRUCTURAL ANALYSIS OF WIND TURBINE BLADE
Mr. Ashneet Pal Singh, Mr. Tauseef Raza, and
Mr. Mohammad Rashid
This project considers the deformation due to the aerodynamic loading of a wind turbine blade by performing a steady-state 1-way FSI (Fluid-Structure Interaction) analysis. Part 1 of this project uses ANSYS Fluent to develop the aerodynamic loading on the blade. In part 2, the pressures on the wetted areas of the blade are passed as pressure loads to ANSYS Mechanical to determine stresses and deformations on the blade. Then the work explores to validate the strength of the blade and to compare analysis for five different materials like Structural Steel, Epoxy Carbon, S-glass, E-glass & Aluminium alloy & select the best material out of these for the wind turbine blade. The ultimate objective of the project is to analyze the various parameters involved in designing of the wind turbine blades through the structural analysis and to calculate an optimum blade shape, for the procedure begins with the choice of airfoils characteristics. Then an initial wind blade design is determined using blade element momentum. The blade plays a pivotal role because it is the most important part of the energy absorption system. Practical horizontal axis wind turbine (HAWT) designs use airfoils to transform the kinetic energy in the wind into useful energy and it has to be designed carefully to enable to absorb energy with its greatest efficiency. There are many factors for selecting a profile. One significant factor is the chord length and twist angle which depend on various values throughout the blade. Computational Fluid Dynamics (CFD) are used for wind turbines airfoils static structural analysis. This differs from the traditional aerospace design process since the lift-to-drag ratio is the most important parameter and the angle of attack is large. CFD simulations are performed with the incompressible Reynolds Averaged Navier–Stokes equations in steady state using a one equation turbulence model. The aim of the analysis is to validate the strength of the blade and compare the above materials to select the best material for the wind turbine blade.
Footstep Power Generation System

Man has needed and used energy at an increasing rate for his sustenance and wellbeing ever since he came on the earth a few million years ago. Due to this a lot of energy resources have been exhausted and wasted. Proposal for the utilization of waste energy of foot power with human locomotion is very much relevant and important for highly populated countries like India and China where the roads, railway stations, bus stands, temples, etc. are all overcrowded and millions of people move around the clock. This whole human/ bio-energy being wasted if can be made possible for utilization it will be a great invention and crowd energy farms will be very useful energy sources in crowded countries. The concept is to capture the normally lost energy surrounding a system and converting it into electrical energy that can be used to extend the lifetime of that system’s power supply or possibly provide an endless supply of energy to an electronic device which has led to power harvesting. One of the most interesting methods of obtaining the energy surrounding a system is to use footstep Power generation. There exists a variety of energy harvesting techniques but mechanical energy harvesting happens to be the most prominent. This technique utilizes various components where deformations produced by different means are directly converted to electrical charge via a DC motor. Subsequently, the electrical energy can be regulated or stored for further use. The motive is to obtain a pollution-free energy source and to utilize and optimize the energy being wasted. In this project, we are generating electrical power as a non-conventional method by simply walking or running on the footstep. Non- Conventional energy system is very essential at this time to our nation. Non- Conventional energy using footstep is converting mechanical energy into electrical energy.
Design And Fabrication Of Compact Paper Recycling Machine
Mr. Saurabh Sharma, Mr. Anurag Sharma, and
Mr. Gaurav Kumar
Due to the lack of proper waste collection channels, we lose a major portion of landfills. The amount of imported waste paper is greater than indigenously collected paper. So, instead of throwing away the waste paper in the trash, recycling can be adopted. In institutes like offices, schools, colleges, and industries the paper recycling machine can be used to reduce paper waste and cost-saving. The main benefit of recycling is a double decrease in the environmental load.
Designing an automatically operated compact recycling machine can be used to simplify the process and reduce the production cost of paper. The machine is designed with essential sections to carry out the process. The 3-D modeling is done in CATIA and the machine will be fabricated accordingly.
