MS Thesis University Of Texas At Arlington BTech University Of Kerala Major: Aerospace Engineering (2015 – 2017) Major: Mechanical Engineering (2011 – 2015) CGPA: 3.5/4 CGPA: 4/4

Skills: C, C++, MATLAB, ANSYS, Fluent, NPSS, Autodesk Inventor, AutoCAD, CATIA, Solidworks Projects

Simulation & Analysis: Numerical Simulation of Stenotic blood vessels (Aug 2014 – May 2015) Blood flow in a human carotid artery affected by stenosis was simulated using ANSYS Fluent. A comparison of different Non-Newtonian models such as Casson, Carreau and Herschel-Bulkley models were used for analyzing stenosis. A velocity profile UDF for flow in blood vessels was developed. Analysis of blood pressure, velocity and wall shear stress for various degrees of stenosis was also performed. Mesh dependent study was done for the best model.

Engine Design: High Bypass ratio Twin Spool Turbofan cycle design (Jan 2016 – May 2016) A high bypass ratio, twin spool turbofan engine cycle was to be developed for a commercial transport aircraft that was to fly from DFW to Seoul. Altitude, cruise Mach number, Sea level and cruise thrust requirements were specified and the engine cycle was designed accordingly using the software, NPSS. Parametric cycle design was performed to obtain an optimum combination of bypass ratio and pressure ratios and an off design performance analysis was also conducted to arrive at the best design.

Systems Engineering: Reverse Engineering the X-43A and X-43C (June 2016 – Aug 2016) The goal of the project was to gather available data on hypersonic aircrafts and use this knowledge to reverse engineer the X-43A and X-43C. I was a member of the Propulsion team and my primary focus was on giving inputs on engine sizing and identifying fuel requirement for the scramjet phase of the mission. The X-43A was reverse engineered, a database for the X-43C was also created from limited resources, mostly by comparison with the X- 51 WaveRider. Ultimately, a proposal was made to modify the X-43C for runway landing.

Simulation & Analysis: Analysis of flow in fluidic valves in a Rotating Detonation Engine (June 2016 – Aug2017) Flow in fluidic valves (FV) in Rotating Detonation Engines is simulated using ANSYS Fluent. A 2D, stoichiometric Hydrogen - Oxygen detonation is simulated using a detailed 19 step chemical mechanism. High pressure products of combustion propagate in the tube and enter the FV, shutting fuel flow off temporarily. Flow resumes when a rarefaction wave lowers the pressure to a value less than the steady state value. Thus a valveless mechanism (no moving parts) is proved to be operational. Time taken for flow to return back to steady state pressure in the FV and the composition of the mixture when this happens are studied. Experience
