Abstract

Undergraduate mechanical engineering students at our school take a first course in ordinary differential equations, but are not obliged to take any courses in partial differential equations. On the other hand, all undergraduate heat transfer textbooks available today never discuss integral methods for solving the governing PDEs in heat transfer, which are superior to the common finite difference method approach taught in the classroom.  In this paper, we present our methodology in bringing such powerful methods to the undergraduate heat transfer classroom with no prior student experience with PDEs. Integral equations together with Ritz and Kantorovich methods are used to show our students in the undergraduate heat transfer course how to find approximate solutions to multidimensional steady and unsteady conduction problems, with better accuracy to that found by finite difference methods under distinct temperature profiles. The approach emphasizes the physical concepts by writing the first law of thermodynamics in integral form and choosing approximate temperature profiles satisfying boundary and initial conditions. In addition, the mathematical implications of using integral methods in this undergraduate course show students the value in reducing the order of the governing PDEs and/or the number of associated independent variables.  No knowledge of separation of variables or transform methods is needed to obtain a more reliable approximate solution to such multidimensional steady or unsteady problems.  We believe that this new approach and strategy are ideal for teaching these senior undergraduates the fundamentals of how to use integral methods to better understand and solve heat transfer problems.
