sonyhome Registered Member Join Date: Jul 2007 Posts: 150	More turbulence links I had done a mini survey on VGs in cleanmpg.com,here, which I'll recap and complement: Vortex Generators - VGs: Mitsubishi EVO MR $300 Air Tabs $2.50/ea (+10% MPG CR-V gen-1) AirFlow Systems $10/25ft (I contacted them on FE and they honestly replied) Vortekz $20/10pc Fuel Savers AU$110/9pc (up to 11% savings) Boundary Layer Energizers etc., not quite VGs: UC Davis BLEs Sinha Deturbulator tape (This claims up to 30% MPG increase, still in R&D) Found in Bman83GL Deturbulator tape topic. Zig-zag and dimple tape(2,3) Spoilers Spoilers (not wings) are used to detach the flow of air from the rear of the car to create a pocket of non-turbulent stagnant air behind the car to finish the air flow like a teardrop (makes a virtual boat tail) and reduce Cd caused by drag from poor rear aerodynamics. Used by modern wedge shaped hatchback cars. (need references) see Citroen Cx or Toyota Prius. Other stuff Aerody.org articles Wolf-Heinrich Hucho - Aerodynamics of Road Vehicles From Fluid Mechanics to Vehicle Engineering Recumbents.com Aerohead's post ecomodder Car Aerodynamics Diffuser (read for front/rear impact on underbody drag) and ground effect Wing and Aerofoil Maxing out tire pressure Drag Coefficient - Cd/Cx Wikipedia listing Daox CdA listing from ecomodder Not aero Driving tips (some usefull A/T tips) Pulse and glide explained with MPG results Autospeed articles As for Autospeed aero articles, I had read a few cool ones (VG experiments, wool tuft testing, airflow test): Vortex: http://autospeed.drive.com.au/cms/A_3061/article.html http://autospeed.drive.com.au/A_3060/cms/article.html http://www.autospeed.com/A_3059/cms/article.html http://www.autospeed.com/A_3058/cms/article.html Aero testing: http://autospeed.drive.com.au/cms/A_108676/article.html http://autospeed.drive.com.au/A_108675/cms/article.html http://autospeed.drive.com.au/A_108674/cms/article.html http://autospeed.drive.com.au/A_108656/cms/article.html Aerodynamics: http://autospeed.drive.com.au/cms/A_107773/article.html http://www.recumbents.com/car_aerodynamics http://www.edmunds.com/advice/specia...4/article.html http://www.ibsinger.com/gallery.htm?...&galleryId=768 Under car airflow (Prius +5MPG): http://autospeed.drive.com.au/cms/A_2456/article.html http://autospeed.drive.com.au/cms/A_2455/article.html Undertrays spoilers and bonnet vents http://autospeed.drive.com.au/cms/A_2162/article.html http://autospeed.drive.com.au/cms/A_2160/article.html http://autospeed.drive.com.au/cms/A_2159/article.html Wiper blade deflector for noise http://autospeed.drive.com.au/cms/A_2445/article.html __________________
