![]() The following parameters of the computational model were considered: the location of inlet and outlet boundaries, type of mesh topology, size of mesh and mesh parameter y +. Two radial impellers was investigated: the high-pressure at ѱ T=0.71 and the low-pressure at ѱ T=0.43. ![]() The presented research was conducted using Numeca Fine/Turbo package with Spalart-Allmaras and Shear Stress Transport turbulence models. ![]() Searching and applying optimal parameters of the grid model, the computational domain and solver settings allows engineers to carry out a high-accuracy modelling and to use computational capability effectively. The article deals with the choice of a grid and computational domain parameters for optimization of centrifugal compressor impellers using computational fluid dynamics. ![]() However, for the successful and productive optimization it is necessary to define a simulation model correctly and rationally. Nowadays the optimization using computational fluid dynamics (CFD) plays an important role in the design process of turbomachines. V V Neverov, Y V Kozhukhov, A M Yablokov, A A LebedevĪbstract.
