Integration a Design of Experiment in the Heat Transfer Laboratory

Abstract

The Design-Build-Test approach was used in developing an experiment for a junior-level heat transfer laboratory. In this experiment, student teams design, build, and test a fin attachment to increase the heat loss from a surface. In the testing phase, the students get the opportunity to compare the measured temperature profiles in the fin to both analytical and numerical (finite difference) solutions. This kind of experience enhances the understanding of the transfer of thermal energy by undergraduate mechanical engineering students and exposes them to several important concepts in heat transfer.

I. Introduction

The Design-Build-Test (DBT) concept has, recently, been used in undergraduate engineering laboratories [1, 2] and also in capstone senior design projects in which students design, develop, build, and test [3]. Traditional undergraduate heat transfer laboratories in mechanical engineering expose the students to heat transfer concepts presented in lecture classes, 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 requires that graduates of engineering programs possess “an ability to design and conduct experiments, as well as to analyze and interpret data” [4] and “an ability to design a system, component or process to meet desired needs” [4]. To meet the requirements of this ABET accreditation criteria, the faculty of the mechanical engineering program at Indiana University-Purdue University Fort Wayne has begun the development of DBT experiments in all required laboratories of the mechanical engineering program. The faculty believes that this approach would enhance and add another dimension to the teaching/learning experience in a laboratory course. One of the first DBT experiments to be developed was a fin attachment design experiment is presented in this paper. A prototype of this experimental apparatus is shown in Figure 1.
