1.	Which of these forces will have to be analysed using CFD to improve the aerodynamic performance of a vehicle?(a) Lift(b) Drag(c) Thrust(d) WeightThe question was asked at a job interview.This interesting question is from Applications in section Philosophy of Computational Fluid Dynamics of Computational Fluid Dynamics
Answer» Right choice is (b) Drag For EXPLANATION: The drag FORCE is the one which pushes a BODY backward during its motion. Therefore, to increase the efficiency of a vehicle, there should be LESS drag.
