Due to their complex shape and complicated flow configuration, the volutes of turbocharger compressors and turbines appear to be a difficult component for both numerical modelling and experimental measurements. This paper presents some 3-D Reynolds Averaged Navier-Stokes (RANS) calculations for a volute with a trapezoidal cross-sectional shape. Flow recirculation under the ‘tongue’ and treatment of radial outflow boundary condition are two important aspects of the current calculations. The results are compared with available experimental data and the reasons for the discrepancies are discussed. The flow features highlight the fact that very strong secondary velocities are present and hence the conventional one-dimensional analyses are not adequate for design purposes. The paper also highlights the typical problems faced by a numerical analyst from grid generation point of view and briefly describes a procedure for handling the problems. Generated grids for two different volutes are presented here in order to show the capability of the grid generation method.
