To optimize the vortex generators for a Venturi-style underfloor tunnel on a Formula One car, focusing on maximizing downforce while minimizing drag at speeds of 200-250 km/h, with a 5-degree yaw angle and 35mm ride height, consider the following:

Vortex Generator Geometry:

  1. Type: Use wing-type vortex generators due to their effectiveness in creating strong vortices.
  2. Angle: Set the angle of attack between 10 to 15 degrees relative to the oncoming airflow to enhance vortex strength without excessive drag.
  3. Height: Maintain a height of 20-30mm to ensure sufficient vortex generation within ride height constraints.

Placement Strategy:

  1. Positioning: Place the generators 200-300mm upstream of the Venturi tunnel exits to allow optimal vortex development.
  2. Spacing: Space them 100-150mm apart to ensure even airflow influence without interference.
  3. Orientation Adjustment: Compensate for the 5-degree yaw by angling the generators 5 degrees in the opposite direction to maintain effectiveness during turns.

Considerations:

  • Balance: Aim for a configuration that maximizes the downforce-to-drag ratio, ensuring efficiency.
  • Testing: Utilize CFD simulations and wind tunnel tests to validate and refine the design, focusing on flow characteristics and performance metrics.

This approach should enhance underfloor airflow, generating strong, stable vortices that improve downforce while keeping drag penalties minimal.
