Modélisation multiphasique et calcul d'interface dans les procédés de mise en œuvre des propergols

Abstract : Improving the determination of the fluid/air interface evolution, we propose an adaptation of a Level Set method. Indeed, we avoid the reinitialization stage by including it in a transport equation model. Moreover a smooth truncation of the distance function by using a sinus filter is proposed. We stabilise the discretization scheme by using a SUPG method. The convected Level Set method created is easily implementable and shows good results as expected. In order to underline the advantages, we present numerical results on classical interface capturing benchmarks. Fluid Buckling is a phenomenon consisting in torroidal oscillations. This phenomenon appears when a high viscosity fluid flows vertically against a flat surface. This phenomenon may occur in industrial situations, like the injection molding of propergol in complex-shaped cavities. These coiling or folding oscillations appeared during the mold filling stage lead to air entrapment. To understand and control this flaw, we use our Convected Level Set method to simulate two-dimensional and three dimensional viscous jet buckling.
