Free convective heat ransfer fro ma heated horizontal surface directly exposed to a liquid into which vertical fins, attached to a cooled surface, project vertically downwards has been numerically studied. It has been assumed that the fins are everywhere at the temperature of the cooled surface. TH governing equations, witten in dimensionless form, have been solved using the finite element procedure. THe solution has the following parameters: the Rayleigh number, the Prandtl number, the dimensionless fin spacing and the dimensionless gap between the bottom of the fin and the lower surface. Solutions have been obtained for a prandtl number of 5 for a wide range of the remaining governing parameters.
