Numerical Study Of The Heat Transfer And Friction Performance In Channels With A Supercritical Fluid

Abstract

This work investigates the applicability of smooth pipe correlations for Nusselt number and friction factor when a supercritical carbon dioxide is used as the working fluid. Predictions of the heat transfer and friction factor are obtained using a computational fluid dynamics approach. The performance of a channel nominally at inlet pressure of 9 MPa and temperature of 1350 K and a channel at 24 MPa and 320 K are explored. The purpose of the investigation is to assess the suitability of bulk channel properties for evaluating the performance of channel flow where the fluid is in the supercritical phase. Numerical results indicate that bulk properties can reasonably predict the friction factor and Nusselt numbers with reasonable accuracy using existing correlations.
