Effects of processing parameters on the convective heat transfer rate during ultrasound assisted low temperature immersion treatment of a stationary sphere
TL;DR: In this article, the effect of ultrasound irradiation on the enhancement of convective heat transfer between a stationary copper sphere and cooling medium was experimentally studied at different Re and Pr numbers and the largest values of the enhancement factor were observed for low values of re and pr which demonstrated a better efficiency of ultrasound radiation at higher viscosities and lower flow rates as a result of its mixing and cavitation effects.

Dimensionless correlations for forced convection in liquid metals : Part I. Single-phase flow
TL;DR: In this paper, a dimensionless heat-transfer correlation for single-phase flow forced convection in liquid aluminum has been derived using a novel experimental method, in which an aluminum sphere was rotated with a specific tangential velocity and its melting time was measured and correlated with the convective heat transfer characteristics.

Numerical study on laminar free convection heat transfer between sphere particle and high pressure water in pseudo-critical zone
Liping Wei,Youjun Lu,Jinjia Wei +2 more
TL;DR: In this article, the steady free convection heat transfer around a single sphere particle in high pressure water of pseudo-critical zone was carried out, and both the Boussinesq approximation method and real properties model (considering variable specific heat, density, viscosity and conductivity of supercritical water) were incorporated to simulate the flow and temperature field.
