Projects

Solving the steady and unsteady 2D heat conduction problem in MATLAB, Skill-Lync

The Heat conduction equation is solved for both steady and transient conditions.

The Jacobi, Gauss-seidel, Successive over-relaxation is the iterative techniques that are used to solve the equation.

The MATLAB code is written for both implicit and explicit techniques.

Solved Quasi 1D supersonic Flow through a Convergent Divergent Nozzle.

Wrote MATLAB code to solve 1D governing equations in the conservative and non-conservative form.

Implemented the Mac-Cormack method for second-order time accuracy.

Implemented a Courant number-based time step controller.

Simulation of Flow through a pipe in Open Foam, Skill-Lync

The ico Foam solver is used to simulate the flow in the pipe.

Wrote MATLAB that can generate the computational mesh automatically for any wedge angle and grading schemes.

The simulation is done for the wedge section of the pipe on giving axisymmetry condition.

Ahmed Body Challenge using ANSYS FLUENT, Skill-Lync

The grid dependency test on the Ahmed body on varying mesh size and pressure, velocity plots are done for comparing the results.

An enclosure is created around the body so that extra refinement can be done for getting accurate values.

Inflation layers on the surface of the body to increase the accuracy of the results.

Conjugate Heat Transfer Analysis on a graphics card, Skill-Lync

A steady-state heat transfer solver used to analyze the graphic card model and a grid dependency test is done.

The maximum temperature of the processor and heat transfer coefficient at appropriate areas of the model are calculated.

The potential hotspots on the model are identified and temperature, velocity plots are done for different grids.

Challenge on Gearbox Sloshing effect, Skill-Lync

The 2-D simulation is used to study the flow pattern of the two different fluids.

Two different clearance volumes of the gearbox are used in the simulation.

The reports of the behavior of fluids are achieved and animations are done for all the cases.

Cyclone Separator Challenge, Skill-Lync

The performance and analysis on the cyclone separator are done with different boundary conditions on the inlet.

The steady-state condition with the k-epsilon viscous model is used.

Two types of particles with different sizes are introduced at a time into the cyclone separator for knowing the efficiency.

Challenge on Combustion, Skill-Lync

The combustion simulation is conducted on the combustor model, Methane is used as the fuel and according to the stoichiometric conditions, the air-fuel ratio is maintained.

The different species mass fractions and temperatures results are collected at different locations in the model with the help of line probes.

Reaction Mechanism Reduction Project using Python and Cantera, Skill-Lync

Reduced the number of mechanisms in the GRI3.0 for calculating the Ignition-delay and Maximum temperature.

Methane is used as a fuel, it is burned in the stoichiometric conditions, and the Ideal Gas constant pressure network model is used.

The tolerances that are used for reducing the mechanism for calculating ignition-delay and maximum temperature is 5%.

Sensitivity Analysis Assignment, Skill-Lync

Got the top ten sensitive reactions in the gri.30 mechanisms for solving in the combustion of methane within the specified time.

For every time step, the top sensitivity value is taken at the end the values are sorted and the top ten values are plotted.

The Ideal Gas Constant Pressure network model is used and methane is used as a fuel.

1D Flame Speed Analysis, Skill-Lync

The 1D Flame speed simulation is done for a premixed mixture in a shock tube. It is assumed as a steady-state because we are using the laminar flame in 1D.

The Free Flame model is used for solvation, two mechanism files are used for the comparison GRI3.0 and H2_mech, and results are plotted.

Autoignition using Cantera, Skill-Lync

The first part of this project is divided into two cases in which either one of the parameters in temperature and pressure kept constant and other parameter changes within a range.

The second part of this project is divided into two cases in the first case the temperature is set to 1000K and in the other case it is set to 500K and pressure is kept constant for 5atms. The main aim of this part is to check whether the auto-ignition happens in both cases or not.

Combustion Efficiency Calculation after Preheating, Skill-Lync

The effects of Preheating are analyzed by considering three parameters Adiabatic flame temperature, combustion efficiency, and percentage of saving the fuel.

The python codes are written separately for analyzing each parameter by using the Cantera module and the results of before and after preheating were compared through plots.

The Ideal Gas Reactor network model is used and methane fuel is burned under stoichiometric conditions.

Experimental investigation on magnetic induction technique to overcome the rigidity in using butanol as an alternative fuel, M. Tech Project

Enhanced the complete combustion of alternative fuel in internal combustion engines.

To achieve these, magnets are used for ionizing the fuel which will enhance the combustion by increasing filterability, reducing surface tension, and increases the interlocking capacity of oxygen within the fuel.

Alcohol blends are used as alternative fuel because of it properties nearer to diesel fuel.

Published the project in Journal of Emerging Technologies and Innovative Research

Suitability of pumpkin seed oil methyl-ester as an alternative fuel for compression ignition engine, B. Tech project

The project involves extracting oil from pumpkin seed, converting oil into Biodiesel through Transesterification process and different blends are tested in the engine.
