Control of Shocks in CFD

  • Claude Bardos
  • Olivier Pironneau

Summary

Shock Control is a type of inverse problem for which the most suited solution method seems to be least square and optimal control algorithms (see [8]). As control theory assumes differentiability, there are mathematical difficulties when the modelling uses a system of conservation laws like the shallow water or Euler equations (see [15] for example). In this paper we study the differentiated equations of some equations of Fluid Dynamics and show that Calculus of Variation can be applied and control problem can be solved numerically more or less as usual, provided derivatives are understood as distributions.
