Abstract

The objective of this paper is to develop and present a correlation equation for the average heat transfer coefficient associated with long horizontally oriented circular fin rods that accounts for the effect of both modes of heat transfer: convection and radiation. Four aluminum circular cross-section test rods with diameters of 3.18, 6.35, 9.53, and 12.7 mm were used to develop such a correlation equation. This correlation will be supplied to the students to be used in the design of a fin attachment using the Design-Build-Test approach.

I. Introduction

Heat transfer is a very important subject and has long been an essential part of mechanical engineering curricula all over the world. Heat transfer is encountered in a wide variety of engineering applications where heating and cooling is required. Heat transfer plays an important role in the design of many devices, such as spacecrafts, radiators, heating and air conditioning systems, refrigerators, power plants, and others.

Traditional undergraduate heat transfer laboratories in mechanical engineering expose the students to heat transfer concepts learned in the classroom, but do not provide them with design experiences similar to what they might face as thermal engineers in industrial positions. In addition, the Accreditation Board for Engineering and Technology (ABET) accreditation criteria require that graduates of engineering programs possess “an ability to design and conduct experiments, as well as to analyze and interpret data” [1] and “an ability to design a system, component or process to meet desired needs” [1].

Very recently, the Design-Build-Test (DBT) concept was suggested by Abu-Mulaweh [2] to be used in creating an experiment for a junior-level heat transfer laboratory. In that experiment, student teams design, build, and test a fin attachment to increase the heat loss from a surface. Extended surfaces (fins) are used to enhance the heat transfer rate between a solid surface and adjoining fluid. The fin is a good application that involves combined conduction, convection, and radiation effects.
