Experimental and computational Studies on vehicle aerodynamic drag Reduction by vortex generators

Abstract

The rapidly increasing fuel prices and the regulation of green house newlinegases to control global warming have given tremendous pressure on the newlinedesign engineers to enhance the current designs of the automobile using newlineminimal changes in the shapes To fulfill the above requirements design newlineengineers are using the concepts of aerodynamics to enhance the efficiency of newlineautomobiles This brings the idea of using external add on devices which newlinecould be attached to the present vehicle without any modifications newlineThe present research is carried out to study the variation of pressure newlineCoefficient dynamic pressure coefficient of lift and drag with and without newlinevortex generators VGs in a utility vehicle by varying the design variables newlinesuch as interval to height I H ratio newline newline
