Integration of Simulation into the Undergraduate Fluid Mechanics Curriculum using FLUENT Rajesh Bhaskaran, Lance Collins Cornell University Ithaca, New York
Abstract The objective of this eﬀort is to integrate simulation technology into the intermediate-level ﬂuid mechanics course in the undergraduate mechanical engineering curriculum at Cornell University. This is achieved using FLUENT, an industry-standard computational ﬂuid dynamics (CFD) package. We seek to expose students to the intelligent use of CFD as well as use FLUENT as a virtual lab environment for hands-on exploration of ﬂow physics and reinforcement of fundamental concepts. Prior to introducing students to FLUENT, we illustrate the underlying numerical concepts such as discretization, grid and iterative convergence, stability, etc. on a simple one-dimensional equation. The classroom examples we have developed are: laminar and turbulent ﬂow in a circular pipe; compressible ﬂow in a nozzle; and ﬂow past an airfoil. In the pipe ﬂow exercise, students are taken through the steps in simulating steady, incompressible, viscous, developing ﬂow in a pipe at low and moderate Reynolds numbers. The concept of turbulence modeling is introduced. Results at the pipe exit are compared with classical results for developed ﬂow (laminar and turbulent) taught in our introductory course in ﬂuid mechanics. The nozzle ﬂow example simulates the high-speed, inviscid airﬂow through an axisymmetric converging-diverging nozzle. Results for the isentropic case are compared with the classical quasi-one-dimensional results. A non-isentropic case with a shock wave in the diverging section is also presented. In the airfoil example, students simulate inviscid as well as turbulent ﬂow over an airfoil. The lift-curve is compared with thin-airfoil theory. The emphasis of the examples is on the understanding of the solution procedure, and the analysis and justiﬁcation of results. Our experience demonstrates that FLUENT can be a valuable tool in teaching the proper use of CFD as well as important physical principles at the undergraduate level. The use of hands-on simulations and a rich visual environment facilitates learning of abstract concepts and stimulates student interest.
Introduction Within the last ﬁfteen years, computer-based simulation has become an integral part of design, analysis and research in ﬂuid dynamics. As in other ﬁelds of engineering, the in- creasingly widespread use of computation has been driven by the dramatic reduction in the cost of computing hardware and the maturing of oﬀ-the-shelf, commercial software pack- ages. Despite the prevalence of computational ﬂuid dynamics (CFD) software in industry and research, their use in our undergraduate curriculum has been slight to non-existent.
