AbstractIn this paper, we introduce a three-equation turbulence model with the charactenstic time scales intrinsic to turbulent swirling flows incorporated. In addition to the conventional two equations of kappa and epsilon, another equation on the turbulent eddy viscosity is solved. We discuss pros and cons of the proposed model by applying it to the typical swirling flows, that is ,a swilring flow in a straight pipe, and a flow through wingtip, and found that by using the newly proposed three-equation model we can predict the swirling flow characteristics more accurately even with the RANS approach.
