- W569155245 abstract "The objective we have set ourselves for this these is to solve two problems dealing with the « moving boundary problems » : Direct problem : In this part, we have establish a relation called « Moknine equation», it gives us the ability to produce the exact solution of the moving boundary problems, the procedure consists of dividing the formulation into two ones, at the first the solution without accounting the discontinuity at the moving boundary is easily calculated, and eventually the final solution that corresponds to the discontinuity is concluded. To better illustrate the methodology, the case of solid liquid phase change problem is considered. Inverse problem: in order to govern a solidification process, the thermal parameters at the moving boundary are prescribed (velocity, thermal flux and the interface form), and the beat flux at the fix boundaries to makes the desired behaviour is estimated, the technical used to solve this inverse boundary problem is the space marching method. As a consequence, of the difficulties accounted to apply the Weber and M. Raynaud schemes due to the moving boundary, a new scheme is proposed. It is applied in the case of ID and 2D cases. It’s fiability is demonstrate through a numerical simulation" @default.
