Research & Publications
Undergraduate Research Assistant (April 2013 – May 2014)
Research Topic: Effect of Location of Cambered Spoiler on Aerodynamic Characteristics of a Car.
Supervisor: Dr. Khandaker Aftab Hossain
Research Focus: Numerical investigation of the aerodynamic stability of a car by evaluating different cambered spoiler positions using CAD and CFD software. The research demonstrated that rear spoiler placement generates greater downforce than rooftop placement, improving vehicle traction and stability.
