Classical free-streamline flow over a polygonal obstacle
This paper presents a practical method for computing flows over arbitrary polygonal obstacles to high accuracy in a few seconds of computer time. We achieve this high speed and flexibility by working with a modified Schwarz-Christoffel integral that maps onto the flow region directly rather than onto the log-hodograph polygon. This integral and its associated parameter problem are treated numerically by methods developed earlier by the second author [SIAM J. Sci. Stat. Comput. 1, 82-102 (1980; Zbl 0451.30004)] for standard Schwarz-Christoffel maps.
