The present paper reports on the numerical simulation of the transonic laminar flow past a hemisphere cylinder at an angle of incidence of 0 and 19 deg. In both cases the computations suggest unsteady flow behavior which requires further investigations, in particular because other applications by similar methods in two and three dimensions do allow to simulate symmetric transonic and steady supersonic flows. One instantaneous flow result for the 19 deg case is used as an example to analyze the topology of a flow with separation. The analysis shows that the numerical simulation yields results consistent with possible topological structures, and can be used further to investigate steady state flows with separation.
