摘要

The normal shock at a curved surface in transonic flow leads to a superdetermined boundary value problem. A bump behind the shock decreases the drag of the airfoil and reduces the necessary energy.Flows of non-Newtonian media lead in the contrary to subdetermined boundary initial problems. The energy bal-ance for these fluids is of great interest for chemical engineering.
