Abstract: Manufactured compressor blades deviate from their intended design, leading to a shift in the mean and scattering of aerodynamic performance. To mitigate performance deterioration without increasing manufacturing costs, an ...

Abstract: In this article, an efficient time–space multigrid (TS-MG) method for solving the harmonic balance (HB) equation system is proposed. The principle of the time–space multigrid method is to coarsen grids in both space and ...
