- W4387144473 abstract "Abstract This paper investigates the potential multimodality of a radial compressor optimization problem by comparing gradient-free and gradient-based methods in terms of results and computational cost. The turbomachinery application consists in a multipoint optimization of the well-known SRV2 radial compressor. The objective of the optimization is to maximize the total-to-total efficiency of the compressor at peak efficiency while maintaining the operating range of the original impeller. The geometry of the compressor is parametrized using 44 design variables and the fluid domain is automatically discretized using a multi-block structured mesh. The evaluation of the aerodynamic performance is performed using a steady-state RANS CFD solver with the Spalart-Allmaras turbulence model. Gradients of the cost functions with respect to the design variables are, when needed, efficiently evaluated with a discrete adjoint solver. Multimodality, i.e. the existence of multiple local optima within the design space, is currently widely debated and plays an important role in the selection of the optimization method. The present study shows that both optimization algorithms converge to the same solution which seems to suggest that the design space is unimodal for the considered optimization problem." @default.
