Coupled analysis of heat transfer and flow of supercritical water in vertical tubes

Convective heat transfer of supercritical water is coupled with flow due to the sharp variation of thermo-physical properties in the neighborhood of the pseudo-critical temperature. The coupled analysis of heat transfer and flow of supercritical water is performed. Based on the analytical results, buoyancy and acceleration effect both reduce the Reynolds stress in the boundary layer due to increase the pressure grads in the bulk kinetic position. The empirical correlations of heat transfer are feasible and applicable which involve the coupled connection of convective heat transfer and flow of supercritical water. (author)
