Mixed convection heat transfer from a particle in supercritical water
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...

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. |
