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...
