ANALYSIS OF AIR FLOW OVER A FORMULA REAR WING
PROJECT
HEMANTH KUMAR BALASUBRAMANIAN
OBJECTIVES
• Study the characteristics of air flow over the rear wing• Reduce the drag as much as possible• Increase the downforce as much as possible• Improvise
ASSUMPTIVE PARAMETERS
• Arbitrary Wing Design• Non-conformity to any standards• Mesh quality assumed to be perfect• Steady State
MODEL
ZOOMED
MESH
ZOOMED
BOUNDARY CONDITIONS
BC & SOLVER OPTIONS LISTED
• Inlet @ 87.5 m/s• Outlet @ static pressure• Fluid domain @ 25C• Wing surface @ 30 C• Inflated wing surface; free wall fluid domain.• K-Epsilon model• Buoyant flow• Accuracy Order – 1E4• Iterative limit – 100.
SOLVING PROCEDURE
• Multiple iterations with locked boundary conditions• Variable: Angle of attack• Parameters of study: Drag force and Downforce.
