Abstract

The free streamline problem investigated is that of fluid flow past a symmetric truncated concave shaped profile between walls. An open wake or cavity is formed behind the profile. Conformal mapping techniques are used to solve this problem. The problem formulated in the hodograph plane is decomposed into two non-overlapping domains. Heterogeneous modeling is then used to describe the problems, i.e. a different governing differential equation in each domain. In one of these domains a Baiocchi type transformation is used to obtain a fixed domain formulation for the part of the transformed problem containing an unknown boundary. In the other
