Abstract
An hyperbolic nonlinear PDE arising in turbulence is solved by the techniques of optimal control theory because of its non standard boundary conditions. Because there are 4 unknown functions of 3 variables, this method of solution yieldsextremely large optimal control problems. Conjugate Gradient Algorithms and Finite Element Discretization where employed with satisfactory results. However, a Quasi-Newton method failed to improve computer time.
