Dr. Hossain is an Assistant Professor in the Department of Engineering and Design at Eastern Washington University, Cheney. His research interests involve the computational and experimental analysis of lightweight space structures and composite materials. Dr. Hossain received M.S. and Ph.D. degrees in Materials Engineering and Science from South Dakota School of Mines and Technology, Rapid City, South Dakota.

Martin Weiser is an Assistant Professor in the Engineering and Design Department at Eastern Washington University. He earned his B.S. in Ceramic Engineering from the Ohio State University and his M.S. and Ph.D. in Materials Science and Mineral Engineering from the University of California at Berkeley. He then joined the Mechanical Engineering department at the University of New Mexico where he taught Materials Science, Thermodynamics, Manufacturing Engineering, and Technical Communication. Martin then joined Johnson Matthey Electronics/Honeywell Electronic Materials where he held positions in Technical Service, Product Management, Six Sigma, and Research & Development. He is inventor on a dozen patents and patent applications and has published over 30 papers and book chapters on topics including ceramic processing, Pb-free solder development, experimental design, and biomechanics.

Dr. Saad received his high school education in Lebanon. His B.S. and M.S. were received from Marquette University in Milwaukee, WI. The emphasis of his master’s dissertation was on a finite element analysis of a solder joint under thermal loading. Dr. Saad received his Ph.D. from Washington State University in Pullman, WA. His research focused on the energy dissipation function of an abrasive water jet cutting through steel. In addition to this, Dr. Saad has taught a vast number of engineering classes at many institutions and is currently teaching, among other classes, Statics, Strength of Materials, Dynamics and Senior Capstone at Eastern Washington University.

Professor Durfee received his B.S. and MS degrees in Mechanical Engineering from Brigham Young University. He holds a Professional Engineer certification. Prior to teaching at Eastern Washington University he was a military pilot, an engineering instructor at West Point and an airline pilot. His interests include aerospace, aviation, professional ethics and piano technology.

Abstract

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.
