    Abstract
  • For the purpose of researching the effect of surface roughness on flow transition and heat transfer of turbine blade, a roughness modification method for γ-Reθ transition model was proposed through self-developed CFD code. Verification was conducted referring to the experimental data of flat plate and turbine vane cases, and satisfactory results were obtained. Taking surface roughness effect into consideration, No. 5411 working condition of Mark Ⅱ turbine vane was simulated and the result was analyzed in detail. Main conclusions are as follows: surface roughness has little effect on heat transfer of laminar boundary layer, while it has considerable effect on turbulent boundary layer. Compared with smooth surface, 5 μm equivalent sand roughness increases the suction side wall temperature by about 5.7 K in turbulent boundary layer, while 100 μm roughness increases the temperature by about 28.4 K, reaching an increase of 5%. Under low roughness degree, effect of shock wave on boundary layer transition process of suction side plays a dominant role, while after reaching a critical degree, effect of surface roughness abruptly changes the transition position, and the critical degree is around 150 μm in the current case.
