| Abstract: | A new LU-type implicit scheme and an improved fourth (fifth)-order high resolution MUSCL TVD scheme were used to solve the full three-dimensional Navier-Stokes equations and the q-w low- Reynolds- number two-equation turbulence model in turbomachinery. The three- dimensional viscous flow field in NASA ROTOR-37, which had been measured by LDV for detail, was evaluated by the present method with the aid of three-dimensional grid generation code based on geometry method combined with PDE solver. The computational results compare well with experimental data. |
