Base on the standard k-ω turbulent model, numerical method for solving three dimensional Reynolds Averaged Navier-Stokes(RANS) was adopted to study the aerothermal characteristics of the turbine blade with casing relative motion. Experimental data were used to verify the effectiveness of the numerical method and turbulent model.The effect of blade tip clearance, geometry and relative motion on blade tip aerothermal characteristics were analyzed.The numerical results show that for the flat tip, r... 相似文献
