• The direct aerodynamic problem of flow on a S2-streamsheet is solved by iterative method of quasi-inverse problem in this article. At first, adopting the nine-point iso-parameter element to discritize the variational principle of quasi-inverse problem about the flow on S2-streamsheet and then the system of equations about stream function is solved after adding the boundary condition. And the calculations for the isoentropic flow and non-isoentropic flow on S2-streamsheet are carried out. Two cases of flow where the variation of entropy along the streamline are supposed to be linearly are calculated.
