Abstract

A new low-Reynolds-number k - ε turbulence model for calculations of flows in pipes has been suggested. It is a modification of a selection of the  k - ε models aimed at fine tuning of the model to predict forced convection heat transfer as well as having a capability to cope with the flows where the influences due to buoyancy are very marked. The new model satisfies these objectives and proves to be sery reliable rnodel in the case of turbulent flows in pipes.
