Meeting Name

1st Annual UMR Undergraduate Research Symposium (1991: Apr., Rolla, MO)


Computer programs were developed to visualize irrotational flow over bluff bodies (circular cylinders and half-bodies) and streamlined bodies (elliptical cylinders and airfoils). The method of superposition of flows was used, with stream functions or complex velocity potentials for fundamental flows being added to obtain the flows over the bodies. For the flow over the circular cylinders, half-bodies and elliptical cylinders, the stream function was calculated directly. The flow over the airfoil was obtained by Joukowski mapping of the imaginary part of the complex velocity potential for flow over a circular cylinder.

The programs developed will be valuable learning tools for undergraduate aerospace engineering students. The students will be helped to understand the equations used to describe the flows by studying the effects of varying various parameters. Future work on these programs may include modifying them to calculate and plot the velocity and pressure distributions, and to calculate the aerodynamic forces on the bodies.
