abstract

Exact inflow conditions for DNS and LES can be generated by resource-intensive precursor simulations of three-dimensional periodic boxes or infinite channels, in the case where a wall-bounded flow is investigated. A cheaper and much more flexible alternative is the use of synthetic boundary conditions. In the proposed paper, a modified synthetic-eddy-method will be presented, which suits the demands and specifications of turbo-machinery applications. It will further be extended to subsonic compressible flows by adding a mechanism to uncouple acoustic waves. It is applied to synthetically reproduce the wake of a turbine test case and validated against the original cascade simulation which is presented in the according Part B paper. This highly flexible approach also provides interfaces to prescribe unsteady inflow conditions, by temporally changing velocities, Reynolds stresses, and turbulent length-scales.
