| Abstract: | This paper is concerned with the hydrodynamic behaviour of the molten powder in meniscus zone, when the solidifying shell is considered an elastic medium. The physical problem is modelised by the coupled system: Stokes and Sophie-Germain equations. A variational approach of the problem allows us to obtain existence, uniqueness and regularity results. The variation of the pressure of the molten powder with respect to its viscosity is studied. We propose an algorithm to determine the maximum value of the viscosity which corresponds to a desired configuration of the molten powder flow. |
