Abstract

Computed transitional and turbulent boundary layer heat transfer results are compared to experimental data. Focus is on the appropriate choice of existing transition models and curvature corrections to the MLH turbulence model. The hypothesis tested is that only the turbulence model need be corrected for convex curvature - the transition model need not. First, the best transition model of the models tested is found by comparison to flat-wall data. The two MLH curvature modifications to the standard MLH turbulence closure model are next compared to a fully-turbulent, convex-curved data set to select the better one. The combined model, with transition and curvature modeling, is then shown to accurately predict convex-curved transition data when the free-stream turbulence intensity is large (2%). A curvature correction to the transition model is needed when the turbulence intensity is lower (0. 68%), however.
