I am a Mechanical Engineer with a PhD degree. My focus is on thermal-fluid sciences, product design, computational fluid dynamics (CFD) and finite element analysis (FEA). I do freelancing to curb my curiosity. Happy to have a chat over projects! LinkedIn: [login to view URL]

$- Modeled 3D design of a cartridge heater and performed CFD analysis on the mixing of two liquids in the heater using free and opensource CFD software OpenFOAM. - Evaluated the time required for one liquid to replace the other liquid completely out of the heater. Calculated the volume fraction of the liquid at the end of each time period to evaluate the volume of liquid required to completely replace the other.$

CFD Simulation of Mixing of Two Liquids in a Catridge Heater

- Analysis on 3D models of cemented hip prosthesis to evaluate the regions of maximum stress. Performed fatigue analysis to estimate the fatigue life of the prosthesis. Optimized the design to withstand higher stress levels.
- Tested the model using Stainless-Steel alloys, Cobalt Chrome alloys and composites and compared their performance under similar loading conditions.

Finite Element Analysis of Composite Hip Prosthesis

- Designed, fabricated and assembled a solar powered Stirling engine to operate at a minimum temperature difference of 14C. Pre-design discovery, 3D designing and prototype modeling were major responsibilities.
- Obtained a stable engine rotation speed of 138 rpm at 14C temperature difference and observed speeds ranging from 140 rpm to 375 rpm at temperature difference range of 14C to 40C.

These designs were not my original idea. My idea was only to make a stirling engine that would run under small temperature difference and I had taken a lot of help from internet and other students who had worked on this before.

Now similar models are sold at various online sites starting from $99.
