Abstract

Periodic fully developed turbulent flows with heat transfer from an inner pipe in the artificially roughened annulus are analysed by the k-ε equation model. A new streamline curvature correction model of eddy viscosity and cyclic TDMA are applied in order to increase the accuracy and converging rate of numerical solutions. This paper illustrates the new method of obtaining the roughness functions from numerically predicted velocity and temperature profiles. A predicted roughness function related to the velocity profile agrees well with previous semi-empirical correlations, but that for the temperature profile shows a different shape from the previous ones.
