GRADUATE RESEARCH AND TEACHING EXPERIENCE

Motorsports Research Lab [Advisor: Dr. Mesbah Uddin] Charlotte, USA, Jun 2016 – August 2018 Numerical investigations on the aero. of ground vehicles in platoon using the fastback DrivAer model (Thesis)

Intended on developing a baseline simulation methodology for examining vehicle interactions

Prepared a commercial type fastback car geometry (DrivAer)

Analyzed interference effects on wake development and drag on cars in platoon using Overset mesh

First ever CFD analysis of vehicle interactions using detailed car geometries Teaching Assistant

Mentored and guided over 150 students in engineering techniques, data collection and processing

Trained the students in tire mounting, balancing and wheel alignment techniques

Guided the students in writing Matlab codes for vibration analysis of systems and to fit Pacejka curves for tire modeling & analysis

Thermal management of a power plant exhaust system and pipeline using CFD

Modeled the exhaust system and pipelines of a power plant that produces roughly 3.6MW of power

Troubleshot thermal breakdown and back pressure issues

Designed a new exhaust pipeline to reduce pressure losses while maintaining heat recovery Influence of CFD setup on simulation results with tandem bluff bodies

Detailed the influence of numerical models, turbulent levels and meshing strategies

Outlined the inefficiency of quasi-steady methods and RANS models in simulating cases with multiple bodies Construction of scaled-model open-circuit suction type wind tunnel

Provided wind tunnel design support and engineering drawings

Hands-on support during construction of plugs for the wind tunnel parts

Trained in fabrication techniques using fiberglass and wood PROFESSIONAL AND ACADEMIC EXPERIENCE
