I went over to Mulsanne's Corner and found the following which was at the bottom of an article on the Toyota GT One.
Mulsanne's Corner: GT-One, 101?
This is a hot topic here at ecomodder. There have been countless arguments, experiments and claims regarding VG's and base filling drag reduction but no one has been able to find any research on the topic. The is one small reference in Hucho but that's it. Do you know where these studies were published? |
I messaged Juha and he had a number of references to look into:
Hucho, "Aerodynamics of Road Vehicles", 1st English edition, page 334, chapter 8.5.4.5 Add-on devices on the rear end...
Hucho refers to: Young, R.A. "Bluff bodies ion shear flow". PhD Thesis, Cambridge University...
.... found another one also referring to the Young work:
SAE paper 2003-01-3377 "Simple and Low-Cost Aerodynamic Drag Reduction Devices for Tractor-Trailer Trucks"
SAE Paper 2005-01-3526 "An Assessment of Drag Reduction Devices for Heavy Trucks Using Design Experiments and Computational Fluid Dynamics"
