Methods of Reducing Vehicle Aerodynamic Drag [PDF]

open access: yesVolume 1: Symposia, Parts A and B, 2012
A small scale model (length 1710 mm) of General Motor SUV was built and tested in the wind tunnel for expected wind conditions and road clearance. Two passive devices, rear screen which is plate behind the car and rear fairing where the end of the car is aerodynamically extended, were incorporated in the model and tested in the wind tunnel for ...

An aerodynamic drag model for protein ions [PDF]

open access: yesJournal of the American Society for Mass Spectrometry, 1994
The energy losses of protein ions passing through a collision cell filled with inert gas have been modeled as the aerodynamic drag on a projectile at high Knudsen number. When applied to the energy loss data of Covey and Douglas (J. Am. Soc. Mass Spectrom.
