Two-Equation Thermal Model for Heat Transfer Predictions
Abstract
The very high temperature level reached in actual turbine components requires accurate simulation tools to predict the heat transfers. The turbine flow is very complex. it is dominated by high pressure gradients, three-dimensional viscous effects, and high heat fluxes. Moreover, the turbulence plays a major role in the heat transfer level. Very efficient turbulence models have been developed for the prediction of dynamic flows. Modelisation of thermal field is relatively inferior to the modelling of dynamic field. The current practice is to use assumption of constant turbulent Prandtl number. The objective of this work is to develop and assess thermal flux models for turbine aerothermal field prediction 1.
