Use of optimal control theory for the numerical simulation of transonic flow by the method of finite elements
It is shown that the transonic equation for compressible potential flow is equivalent to an optimal control problem of a linear distributed parameter system. This problem can be discretized by the finite element method and solved by a conjugate gradient algorithm. Thus a new class of methods for solving the transonic equation is obtained. Il is particularly well adapted to problems with complicate two or three dimensional geometries and shocks.
