Abstract
Experimental study is conducted in order to investigate the feasibility of controlling spiral vortices which appear in the transition process of the boundary layer on the surface of a cone rotating around its symmetrical axis in still air. It is shown that the number of spiral vortices, which is 26 without excitation, can be controlled from 18 to 80 through acoustic excitation.
