Summary

Conjugate natural convection heat transfer from a vertical plate has been investigated analytically and experimentally. Assuming the existence of a vertically averaged interfacial temperature between plate and fluid, it is shown that there is a unique non-dimensional parameter to characterize the problem. The interfacial temperature is obtained as a root of 5th order polynomial for laminar and natural convection. For turbulent convection, the polynomial becomes 4th order. An experiment, using a water vessel with a heating plate on a side wall, was carried out in order to test a proposed theory for the heat transfer. Three different materials, copper, stainless steel and ceramics, were used as a conductive slab.
