Abstract

Using Familiar Analogies to Teach Fundamental Concepts in Thermal and Fluids CoursesAbstractBy the time engineering students enroll into Thermodynamics, Fluid Mechanics, and HeatTransfer courses, they are relatively savvy with math and basic science concepts. Therefore, thecalculations required in the Thermal-Fluids courses are not especially difficult. Conversely,many of the fundamental concepts and physical understanding of energy, fluid mechanics, andheat are difficult to grasp. The students have observed solid mechanical kinematics anddynamics first-hand all of their lives, but energy, fluid flow, and heat flow are not readily visibleand apparent to the eyes.With this in mind, a useful method to explain the concepts is via everyday/familiar/folksyanalogies. This paper contains a sampling of some analogies that can be used to teach thermalfluid concepts as varied as entropy, the no-slip condition, velocity profiles & boundary layers,numerical marching solutions for heat flow, and more. The authors also offer advice for creatingyour own analogies, and intend for the reader to be encouraged to add to the growing list ofteaching analogies.
