Type of article: Article

Summary

A FAST, AND RATHER GENERAL PROCEDURECOMBINING THE SUPERPOSITION PRINCIPLE WITH A FINITE ELEMENT METHOD IS PROPOSED. IT IS EMPLOYED TO CONSIDER THE WALL CONDUCTION EFFECT ON HEAT TRANSFER TO FULLY DEVELOPED LAMINAR FLOW THROUGH A PIPE WHOSE EXTERIOR BOUNDARY IS UNIFORMLY HEATED ALONG A FINITE LENGTH. RESULTS ARE GIVEN FOR TWO VALUES OF EACH OF THE FOUR PARAMETERS DETERMINING THE RELATIVE IMPORTANCE OF AXIAL CONDUCTION: THE PECLET NUMBER OF THE FLUID, THE WALL TO FLUID CONDUCTIVITY RATIO, AND THE DIMENSIONLESS THICKNESS AND LENGTH OF THE HEATED SECTION OF THE PIPE.
