Abstract
Two Reynolds stress transport closures are adopted for modelling flow and heat transfer in fully-developed, axially-rotating pipe flow. Mode lled transport equations are solved for the turbulent stresses and hea t fluxes, and the turbulence-energy dissipation rate. Numerical calcul ations are performed with and without rotation, and the results show t hat both models simulate the strong attenuation of turbulent transport due to rotation. The model solutions are in reasonable agreement with published data and large eddy simulations. Copyright (C) 1997 Elsevie r Science Ltd.
