Heat and Mass Transfer and Physical Gasdynamics

Numerical simulation of heat transfer and turbulant liquid flow in a pipe under supercritical pressure with allowance for the joint effect of density pulsations and thermal acceleration on turbulent transfer

E. P. Valueva

Moscow Power Engineering Institute

Abstract: Regimes of deteriorated (with peaks of the wall temperature) heat release under a turbulent flow of carbon dioxide in a round pipe under supercritical pressure are calculated. The calculation is based on a system of motion, continuity, and energy equations written in the narrow channel approximation. The buoyancy force was neglected. A model of turbulent stress and turbulent thermal flow with allowance for the joint influence of density pulsations and thermal acceleration is proposed. The calculation results for the variation in the wall temperature and resistance coefficients along the well agree with available experimental data. An explanation for the causes of the appearance of a peak in the wall temperature distribution along the pipe in the region where the fluid temperature is close to the pseudocritical temperature is presented.
