Abstract
Abstract: Reynolds averaged Navier-Stokes (RANS) calculations are performed for the GRV-60 radial impeller with an airfoil-type and an unvaned diffusor. For the the airfoil-type aerodynamic diffusor design and off-design conditions are investigated at N = 14000 RPM. Design conditions are investigated at N = 16000 RPM. For the unvaned diffusor design conditions are studied at N = 16000 RPM. Measured total pressure ratios π tot;16 and isentropic efficiency values ηi;16 in [4] are compared with the calculated values. The results are in good agreement with measurements.
