Type of article: Article

Summary

IN THE FIRST PART OF THE PAPER, ERNST SCHMIDT'S INTUITIVE ARGUMENT FOR CHOOSING THE OPTIMUM FIN SHAPE FOR LEAST MATERIAL IS TRANSLATED INTO ANALYSIS USING THE METHOD OF VARIATIONAL CALCULUS. EVEN WHEN THE THERMAL CONDUCTIVITY OF THE FIN IS A FUNCTION OF TEMPERATURE, THE OPTIMUM SHAPE OF AN INDIVIDUAL < HEAT TUBE > OF THE FIN IS THE UNIFORM SHAPE. THIS GENERALIZATION OF SCHMIDT'S ARGUMENT IS USED IN THE SEARCH OF OPTIMUM SHAPES FOR FINS THE MATERIALS OF WHICH HAVE TEMPERATURE-DEPENDENT CONDUCTIVITIES. IN THE SECOND PART OF THE PAPER THE ANALYTICAL GENERALIZATION OF SCHMIDT'S ARGUMENT IS APPLIED TO THE DESIGN OF DUCTS FOR FLUID FLOW.
