Description
  • The work deals with numerical modelling of turbulent flows in channels with an expansion of the cross-section where separation and reattachment of flow occur. The performance of several eddy viscosity models and an explicit algebraic Reynolds stress model is studied. The used test cases are flows in channels with various backward facing steps where the step is perpendicular or inclined and the top wall is parallel or deflected. Furthermore, a channel with the circular ramp is considered. The numerical solution is achieved by the finite volume method or by the finite element method. The results of both numerical approaches are compared.
