Modeling of microporosity, macroporosity, and pipe-shrinkage formation during the solidification of alloys using a mushy-zone refinement method: Applications to aluminum alloys
A microporisity model, based on the solution of Darcy's equation and microsegregation of gas, has been developed for arbitrary two- (2D) and three-dimensional (3D) geometry and coupled for the first time with macroporosity and pipe-shrinkage predictions. In order to accurately calculate the pre...

| description | A microporisity model, based on the solution of Darcy's equation and microsegregation of gas, has been developed for arbitrary two- (2D) and three-dimensional (3D) geometry and coupled for the first time with macroporosity and pipe-shrinkage predictions. In order to accurately calculate the pressure drop within the mushy zone, a dynamic refinement technique has been implemented: a fine and regular finite volume (FV) grid is superimposed onto the finite-element (FE) mesh used for the heat-flow computations. |
