| Abstract: | Numerical simulation of viscous flows through multistage transonic fans was carried out. Three dimensional Navier\|Stokes equations were solved. The accuracy was improved with a high\|resolution scheme. And the convergence was speeded up by the use of LU\|SGS implicit method. The computed results for a highly loaded two\|stage fan at design and off\|design conditions were given in detail. The simulation results show good agreement with experiment data. |
