Experimental studies have been conducted to investigate the effects of the swirl on the turbulent transport of momentum in a concentric annulus with a rotating inner cylinder. Direct measurements of turbulent transport of momentum were made by correlating fluctuations of two velocity components which were detected by a two-color laser Doppler velocimeter. It was observed that the Reynolds stresses increse due to the swirl. The magnitude of the production terms of the transport equations of the turbulent fluxes of momentum were estimated. The dominating terms are pointed out to illustrate the processes of interactions between momentum fluxes and the swirl.
