Steady, inviscid, incompressible, two dimensional flowscontaining vortex patches bounded by vortex sheetsare used to model finite separated regions oncertain closed bodies as an approach to modellingseparation bubbles. First of all the problem of avortex patch on a circle is considered. Calculationswere done for symmetric flows covering a wide rangeof values of the separation position, the strengthof the vortex sheet and the circulation at infinityand for non-symmetric flows at various angles ofincidence. Smooth separation was detected in somecases. This model is used as an intermediate stepfor the calculation of the flow around an ellipseand a Joukowski aerofoil with the use of theJoukowski transformation.
