Krishna Prasad Sah
I am a passionate aerospace engineering graduate with hands-on experience in aircraft and UAV design, aerodynamic simulation, structural analysis, and fabrication. My background includes mentoring in ANSYS Fluent/FEA, contributing to the AIAA Design/Build/Fly team, and leading projects such as Blended Wing Body (BWB) aircraft and twin-boom UAVs.
For my Final year thesis, I conducted numerical simulations of hypersonic Fluid-Thermal-Structural Interaction (FTSI) using OpenFOAM, CalculiX, and preCICE. At the IIT Kharagpur Aerodynamics Lab, I optimized bluff body aerospike configurations for drag reduction at Mach 2.43, validating experimental Schlieren visualization with ANSYS Fluent. Currently, I am working on FSI over flexible moving bodies using OpenFOAM, solids4Foam, and preCICE under supervision of Dr. Chandan Bose.
Backed by strong technical expertise in Python (Machine Learning), C/C++, MATLAB, and CAD/CAE platforms (CATIA, Fusion 360, Blender, X-Plane), my passion lies in leveraging data-driven insights to optimize aerospace systems. I aspire to contribute to innovative projects that push technological boundaries. Let's connect and explore the exciting world of aerospace engineering!
