Heavy Vehicle Aerodynamics: Massively-Separated Turbulent Flow & a Bio-Inspired Device

Abstract

Dr. MacChesney’s doctoral studies focused on improvement of the state of the art in heavy vehicle aerodynamics through computational fluid dynamics methods. Through his research he has devised a drag reduction device inspired by the shape of a harbor seal whisker that reduces drag by up to 22%. Additionally, through application of a novel decomposition method he uncovered a hidden order within massively-separated turbulent flows with evidence that supports a centrifugal mechanism.
