THEORETICAL AND NUMERICAL SOLUTION OF A NEAR SONIC FLOW CONSIDERING THE OFF-DESIGN CONDITIONS
Stodulka J., Sobieczky H.
pages 631 - 634, full text

The work deals with comparison of analytical design methods for transonic flows with modern computational fluid dynamics codes. The theory based on potential flow transformed into modified hodograph plane and simplified by near sonic flow conditions gives an exact solution of a cusped airfoil pointed into the sonic free stream. Results obtained from corresponding commercial ANSYS Fluent inviscid CFD code are compared with this theory on such profile. Because of considerable sensitivity of transonic flows, some off-design conditions in means of different free stream velocities are mentioned and analyzed to see the influence of small changes in boundary conditions on developed flow field.
