• Separated flow past a two-dimensional smooth curved bluff body can be solved by the use of a free-streamline theory so long as the base pressure and the separation position are prescribed as empirical parameters. The purpose of the present paper is to eliminate one of these parameters by determining the separation position as a function of the base pressure with the help of the boundary layer theory. Calculations were performed for cases of a subcritical and a transcritical flow past a circular cylinder. Although some discrepancy is seen to exist between the theory and the experimental data, it is shown that solutions of Kawaguti, and of Bluston and Paulson can be included in the present theory as special examples. Furthermore, a conclusion of the latter paper is criticised from the viewpoint of the present theory.
