Side Pod Vane Development of Perrinn F1 Part 1

on

1. Side Pod Vanes

Type A
Baseline (Perrinn F1 V13)

Type B
One Additional Vane

Type C
Two Additional Vanes

Type D
W08-like

2. Simulation Setup

Wind Speed: 50 m/s
Ride Height: 20mm/50mm (Front/Rear)
Solver: foam-extend-3.2 steady-state solver
Turbulence Model: Spalart Allmaras (+Rotation/Curvature Correction)

3. Forces

SCd = Frontal Area × Drag Coefficient
SCl = Frontal Area × Lift Coefficient
L/D = SCl / SCd
FrDF% = Front Downforce / Downforce
SCl_F = Frontal Area × Front Lift Coefficient
SCl_R = Frontal Area × Rear Lift Coefficient
Mass = Mass Flow Rate Passing Through Radiator

Type D was the best among these 4 specs.
Type B improved front downforce but decreased rear downforce more.
Type C improved front downforce further than Type B but didn't improve rear downforce.
Type D imcreased front downforce and didn't change drag and rear downforce, resulted in better L/D.
