PROJECT EXPERIENCE

Senior Year Capstone Project:

Fabrication and Calibration of five hole probe, NIT Surat Team Leader Aug 2015 – May 2016

Five hole probe is used to find fluid flow velocity component in mutually perpendicular directions.

Pressure values at probe tip are observed by orienting the probe at different angles and in different directions.

The non-dimensional analysis is used to find coefficients.

MATLAB is used to generate plots and algebraic equations.

The open-jet wind tunnel was used as a known field for calibration purpose.

Application in: Internal Combustion engines, Turbomachinery.

Result: Probe with high temperature withstanding capability was made using SS 304 and cost reduced by a factor of 10.

Electric Hybrid Vehicle, NIT Surat Jan 2015 – Apr 2015 Project member

SAE BAJA vehicle was converted to Electric Hybrid vehicle.

Goal: To run the vehicle by an electric motor at low speeds and by the engine at high speeds. Thus, to improve efficiency. Efficiency improved by 3%.

Unique and simple power changing mechanism was used to change the source of power.

Worked on: Power changing mechanism, Dynamic analysis of vehicle.( at which speed gear should be changed, top speed, when to engage engine)

Software used: MATLAB.

Vehicle performance simulation, NIT Surat Sept 2014-Oct 2014 Self-initiated project

GM EV1 and Electric scooter were used for simulation.

Vehicle parameters like weight, motor specifications, battery characteristics were programmed and its performance was simulated when the vehicle is subjected to real world driving conditions.

Software used : MATLAB, Simulink.

Dedicated CNG engine technology, NIT Surat

Project member Nov 2013 – Oct 2014

Goal: To carry out a parametric study of Honda 118 cc Gasoline engine for CNG application.

Worked on: Simulation of engine processes and correlation of experimental data with simulated results.

Software used: MATLAB and C.

Result: Efficiency and power were improved by 15.83% and 4.92% after optimization. SKILLS
