Comparisons the numerical results of the turbulence model for the problem of rotating tubes inside a dynamic hydrocyclone

The article provides a comparative analysis of turbulence models by numerically simulating a swirling flow inside a rotatable pipe. To solve this problem, the Reynolds averaged non-stationary Navier-Stokes equations in a cylindrical coordinate system were used. To find the Reynolds voltage, the turbulence model was used the most popular semi-empirical turbulence model. Comparison is made between models of different approaches to turbulence SSG / LRR-RSM-w2012 and νt-92. The numerical results obtained on the basis of turbulence models are compared with the well-known experimental results of Reich and Beer (1989)
