The Determination of Local Forced-Convection Coefficients for Spheres

Abstract

The local heat-transfer coefficient on the surface of a sphere is investigated in the range of Reynolds numbers from 44,000 to 151,000. Correlation of experimental data is based on the Nusselt and Reynolds numbers, and two curves are presented for the relation between the Nusselt and Reynolds numbers as a function of the angle from the stagnation point.
