轴向旋转管道与旋转射流湍流
Application ID: 140251
Turbulent flow, SSG-LRR interface is used to analyze fully developed turbulent flow in an axially rotating pipe and in a swirling jet emanating from such a pipe. The resulting flow pattern in the pipe is characterized by slower-than-solid-body rotation. Axial velocity of the swirling jet falls off more rapidly at the axis, compared to non-swirling situation, due to the increased outward radial transport of momentum.
SSG-LRR turbulence model is able to qualitatively capture most features of the rotating pipe and swirling jet flows, including axial and tangential velocity, as well as Reynolds stress evolution.
