Control of Transonic Shock Positions
Université Paris VI, IUF and INRIA, France; Pironneau@math.jussieu.fr.
We wish to show how the shock position in a nozzle could be controlled. Optimal control theory and algorithm is applied to the transonic equation. The difficulty is that the derivative with respect to the shock position involves a Dirac mass. The one dimensional case is solved, the two dimensional one is analyzed .
