The nonlinear harmonics (NLH) method allows to simulate unsteady effects in turbomachines when one blade passage (periodic sector) per row is considered. Numerical and computational details of the NLH realization within second-order higher accuracy control volume numerical algorithm for simulations on unstructured meshes are presented. Parallelization aspects and details of computational cost reduction in the parallel heterogeneous code NOISEtte are discussed. The performance of the NLH method is demonstrated on modeling of turbomachinery applications (single rotor Rotor67 and multi-stage compressor). The results are compared with the reference data, both experimental and numerical results obtained by a specialized software.

摘要

The nonlinear harmonics (NLH) method allows to simulate unsteady effects in turbomachines when one blade passage (periodic sector) per row is considered. Numerical and computational details of the NLH realization within second-order higher accuracy control volume numerical algorithm for simulations on unstructured meshes are presented. Parallelization aspects and details of computational cost reduction in the parallel heterogeneous code NOISEtte are discussed. The performance of the NLH method is demonstrated on modeling of turbomachinery applications (single rotor Rotor67 and multi-stage compressor). The results are compared with the reference data, both experimental and numerical results obtained by a specialized software.
