Estimate of total heat transfer in two- and three-dimensional solid bodies utilizing the product of mean temperatures for the intersecting one-dimensional solid bodies

Abstract

The objective of this technical paper is to utilize the product solution method in a direct way to estimate the total heat transfer from (to) two- and three-dimensional solid bodies to (from) surrounding fluids by using the mean temperatures for the intersecting one-dimensional solid bodies. Typical multi-dimensional solid bodies correspond to 2-D large rectangular columns, 2-D finite cylinders and 3-D parallelepipeds. Thermal design engineers, as well as instructors and students in heat transfer courses, will be the direct beneficiaries of the outcome of the technical paper.
