GROUND EFFECTS DIFFUSERS DATA
GROUND EFFECTS DIFFUSERS DATA
(OP)
I’ve searched the internet for a long time for hard data on ground effects diffuser design. Finally I found what I thought was a gold mine: Ground Effects Aerodynamics of Race Cars.
SITE:http://eprints.soton.ac.uk/42969/1/GetPDFServlet.pdf
Actually it’s a review of many ground effects experiments in university wind tunnels, many with moving ground planes. Good stuff.
So I went to page 41, and there it was, the GOLD!: two charts showing lift and drag curves (in the Y axis) as a function of h/d (in the X axis). The variable h is defined (p40, fig. 12) as the vertical dimension of the diffuser entrance, AKA ride height. What about the variable “d” ? No definition or explanation is given, as far as I can tell. Do any of the pros on this site have a clue what “d” is? Thanks, Paul6
