Effect of Side Walls of Wind-Tunnel on Flow around Two-Dimensional Circular Cylinder and Its Wake

Abstract

This paper presents the effect of the side walls of a wind-tunnel on the flow around a circular cylinder and its wake in the N.P.L. type wind-tunnel having the test section of 60×60×310cm. and the dimensions of Karman vortex-street are observed in the water tank. The results are discussed by comparison with those of the investigations so far made.
