Involved in an innovative project for designing an upcoming world's largest structure. Computing with large scale simulations that involve complex physics and numerics Formulating proposals for sub-projects. Implementing several new technologies that reduce costs and increase productivity Effective co-ordination with sub-contractors and university partners.

Successfully implemented a new methodology for Multi-disciplinary, Mulit-objejctive (MDO) aerodynamic optimization of Turbo-Compressors using CFD for aerodynamics and Finite Element Methods (FEM) for structural mechanics. Significantly optimized designs were obtained. Methodology was integrated as standard MDO procedure for Turbomachinery optimization in the organization.

• Developed a simulation framework for evaluating Indoor Thermal Comfort in a generic environment (room, car, aircraft etc) taking into account all physical interactions. • Demonstrated a new methodology of using Functional Mock-Up Units with codes.

Tasks:Generated codes in C language for development of a pre-processor for the in-house CFD code “Keira” at this chair. The task also involved reading and modification of mesh, flow and boundary condition, and other details in CGNS (CFD General Notation System) files for computations.

Performed Global Structural Analysis (FEM) of practical airframe stiffened panels for the fuselage pressure load case of an civilian aircraft. Identified critical location prone to failures.

Performed a detailed Gauge Repeatability and Reproducibility Study (GRR) of used gauges. Identified sources of potential errors.
