1 Numerical and Experimental Study of Microvortex Generators

Publication Summary

A series of experimental and computational studies was conducted on vane-type microvortex generators (MVG) with the aim of better understanding the behaviour and to improve the design of such devices. The traditional rectangular and triangular vanes along with unique NACA0012 and E423 airfoils shaped vanes were studied with a height of 0.2δ while being embedded in a turbulent boundary layer of a flat plate. To assess the reliability of the numerical prediction of the drag forces acting on a MVG, a wind tunnel experiment was conducted. The experiment was conducted at a Reynolds number of 155, based on the friction velocity and the MVG height. A very good agreement was found between the experimental and numerical drag predictions for the MVGs with strong vortices. Fair agreement was found for the two MVGs with weak vortices.
