Desktop Experiment Module: Heat Transfer Adrienne R. Minerick, Dave C. Swalm School of Chemical Engineering, Mississippi State University, minerick@che.msstate.edu

Abstract: This paper outlines a new Desktop Experiment Module (DEMo) engineered for a chemical engineering junior level heat transfer course. This new DEMo learning tool is versatile, fairly inexpensive, and portable such that it can be positioned on student desks throughout a classroom. Advantages of this approach are that students can closely examine and fiddle with the system to see cause and effect better than with instructor led demonstrations. The DEMo system can illustrate conduction of various materials, thermal energy generation, thermal contact resistance, heat dissipation from fins, and convection across surfaces of varying geometry. These learning tools can also serve as vibrant hands-on experiments with high school students.

Introduction:

The junior level heat transfer class is a first course in conduction in 1-D and 2-D systems (Cartesian, cylindrical and spherical coordinates); conduction through composite walls; evaluation of resistances; heat transfer enhancement using fins; convective heat transfer (laminar and turbulent flow, flow past immersed bodies and tube banks); overall heat transfer coefficient, and heat exchanger design. The current course text for this course is Incropera and DeWitt’s “Fundamentals of Heat and Mass Transfer” [1].

Course objectives are to provide junior level undergraduate students with fundamental knowledge of heat transfer in chemical engineering processes and process equipment. Special emphasis is given to the economics of heat exchanger design and heat recovery. It is assumed that students entering the class are proficient in: • Manipulating units in their solitary form or with 1changes such as 1T, • Performing mass & energy balances, • Drawing flow profiles and calculating flow in rectangular and cylindrical geometries, • Physically interpreting a derivative and solving first order linear ordinary differential equations. Throughout the course, students learn and demonstrate the tools, skills and knowledge to: • Distinguish between and apply mathematical models for the three mechanisms of heat flow (conduction, convection, and radiation). • Draw temperature profiles and describe heat flow given system geometry, medium, and direction of temperature gradient. • Calculate rates of heat transfer and analyze data to determine heat flow in various geometries, media, and in common heat exchangers.
