Free convection heat transfer near the leading edge of an isothermal semi-infinite vertical flat plate with finite thickness has been analyzed numerically by the finite difference method for Pr=0.72,The effects of the adiabatic horizontal floor under the leading edge and of the shape of the leading edge on free convection heat transfer have been made clear. When the dimensionless height, H, of the leading edge from the floor is larger than 40,Nusselt number distributions near the leading edge are hardly influenced by the floor, taking lower values than any previous perturbation solutions and being correlated by the following equation : Nux/X^<3/4>=0.356 8+0.120 9 X^<-1.238> X≧1.5 The Nusselt numbers near the leading edge of flat plates with finite thickness are correlated by the Grashof number based on the plate thickness, and the present results for a triangular leading edge agreed well with previous experimental results.
