Abstract

Experimental investigations of loss reduction with riblets have been rnade. Riblets were put on the blade surfaces in different ways in a compressor cascade or on an isolated airfoil. More than 8% drag reduction benefits for an isolated airfoil and more than 10% loss reduction benefits for the compressor cascade have been obtained by using riblets only on blade pressure surfaces rather than on both pressure and suction surfaces.The mechanism underlying these results has been discussed.
