Integration of Numerical and Experimental Studies in a Heat Transfer Course to Enhance Students’ Concept N.M. Hossain, H. Saad, M. Weiser and J. DurfeeThe primary objective of a heat transfer course is to provide the fundamental knowledgenecessary to understand the behavior of thermal systems. This course provides a detailedcalculus-based analysis, including the application of differential equations, of the heat transferthrough solids, fluids, and vacuum. Convection, conduction, and radiation heat transfer in one-and two dimensional steady and unsteady systems are covered. Covering all of these topics in aone quarter course is very challenging to complete in a satisfactory manner. There is very littletime for instructors to incorporate thorough experimental study of each educational item coveredin the class. Therefore, the authors use a combination of numerical and experimental studies tostrengthen the students’ conceptual understanding beyond the classroom lectures.The learning process starts with a one-dimensional heat transfer problem using a straight fin.First, students will learn how to solve for the temperature distribution and heat loss using thestandard differential equations. Then, students will solve the same problem numerically using thefinite element approach. In this case, students will solve the problem using both matrix algebraand the ANSYS finite element package. Finally, students will perform the experiment andcompare the experimental outcomes with analytical and numerical results. Similar learningstrategies will be used for heat transfer from both a sphere and cylinder. Problems will be solvedfor temperature distribution and heat loss using both the lumped capacitance model andnumerical method using ANSYS with final experimental validation. Several parametric analyses,using ANSYS, will also be conducted to extend the students’ understanding into more complexsystems.The learning methodology is a great experience for students to learn numerous heat transferconcept in the limited time available in a one quarter course. The purpose of this paper is toexplain the details of this teaching methodology and discuss the educational outcomes obtainedin our heat transfer curriculum.
