원통면을 따라 마주보고 흐르는 두 곡면벽제트의 상호작용

Abstract

A two-dimensional flow formed by the interaction of the two asymmetric turbulent curved wall jets passed a circuler cylinder is investigated experimentally. The location of the interaction region of the rive opposing curved wall jets, and the flow direction of the merged jet depend primarily on the ratio of the momentum with which the two curved wall jets leave the slots The velocity and the turbulence intensity profiles of the merged jet are quite similar to those of the plane turbulent jet. However, the spreading rate of the merged jet is approximately 1.5 times larger than that of the plane turbulent jet. Also, it is observed that the spreading rate is independent of the momentum ratio.
