Rj. Yang et Wj. Luo, TURBINE BLADE HEAT-TRANSFER PREDICTION IN FLOW TRANSITION USING K-OMEGA, 2-EQUATION MODEL, Journal of thermophysics and heat transfer, 10(4), 1996, pp. 613-620
The proper design of a turbine blade has an important effect on engine
performance and efficiency, The thermal design of a turbine blade is
also greatly influenced by the flow transition phenomena of the bounda
ry layer, Transition in turbine flowfields is a complex process and is
influenced by the Reynolds number, pressure gradient, geometry, and f
reestream. turbulence, etc, In this study, a kappa-omega turbulence mo
del is used to investigate the flow transition as well as problems con
cerned with heat transfer The model predicts well the transition point
and the associated transitional heat transfer coefficients for flat p
late flows. With a suitable surface curvature correction to closure co
efficients of the model, reasonable heat transfer predictions in flow
transition are simulated for turbine blade flows.
