Abstract
Solutions of inviscid rotational flows near the corners of an arbitrary ang le and within a triangle of arbitrary shapes are presented. The corner-flow solution has a rotational component as a particular solution. The addition of irrotatoinal components yields a general solution, which is indetermina te unless the far-field condition is imposed. When the corner angle is less than 90 degrees the flow asymptotically becomes rotational. For the corner angle larger than 90 degrees it tends to become irrotational. The general solution for the corner now is then applied to rotational flows within a tr iangle (Method I). The error level depends on the geometry, and a parameter space is presented by which we can estimate the error level of solutions. On the other hand, Method II employing three separate coordinate systems is developed. The error level given by Method II is moderate but less depende nt on the geometry.
