Description
Summary:This paper aims to study a steady laminar convection flow over a spherical particle in supercritical water in pseudo-critical zone. Forced convection, free convection, assisting convection, and opposing convection from a spherical particle in supercritical water (SCW) were studied based on a numerical model fully accounting for variations of thermo-physical properties in pseudo-critical zone. Variation of specific heat plays a main role in determination of heat transfer coefficient. The gravity direction has a remarkable effect on heat transfer. Quantitative relationship between variable properties and Nusselt number has been established based on the simulation results.
