Steady state RANS approach for numerical simulation of rotating vortex rope in conical diffusers
A novel computationally efficient approach for numerical simulation of helical vortex ropes in axially symmetric diffusers is presented and investigated. It is based on the assumption that the vortex is stationary in the frame of reference, rotating with the vortex core.Alena Romanovna Kocharina +2 more
