A new finite element level set method is developed to simulate the interface motion. The normal velocity of the moving interface can depend on both the local geometry, such as the curvature, and the external force such as that due to the flux from both sides of the interface of a material whose concentration is governed by a diffusion equation. The key idea of the method is to use an interface-...

The effect of impurity interactions on removal efficiency in metallurgical grade silicon (MG-Si) was studied and analyzed to provide a new idea for removing impurities from MG-Si. This paper provides theoretical support the nonmetallic P during purification preparation crystalline silicon. interaction between Al liquid were investigated by directional solidification. effects different pull-down...

This paper aims to describe the experimental framework of Directional Solidification Insert, installed onboard International Space Station, dedicated in situ and real-time characterization dynamic selection solid–liquid interface morphology bulk samples transparent materials under diffusive growth conditions. The observation is an invaluable tool for gaining knowledge on time evolution pattern ...
