Turbulent heat transfer
Abstract
Closure assumptions are defined for a numerical model of an incompressible, twodimensional turbulent boundary layer flow in order to calculate the turbulent heat transfer. The governing equations for continuity, momentum, and energy are formulated, together with the shear stress and heat flux, which has molecular and turbulent components. First and second order closure assumptions, the former being the Prandtl mixing length, and the latter involving balance equations, transport equations, and the Reynolds fluxes, are introduced into a transport equation. The turbulent Prandtl number is modelled and applied to calculate the heat transfer correlations Nu(Re,Pr).
