This work simulates the morphological evolution process of solidification interface silicon crystal. Based on phase field model single dendrite growth pure material in a single-phase system, control equation is re-optimized, and an free energy anisotropy that can simulate competitive multiple crystal grains established. The polysilicon then simulated analyzed. results show when degree undercool...

Seeking high-performance computing methods to solve the problem of a large amount calculation, low calculation efficiency, and small simulation scale on traditional single central processing unit (CPU) platform is great value study micro-structure. In this study, based three-dimensional multi-phase-field model KKSO coupling phase-field solute field, open language (OpenCL) + graphics (GPU) heter...

Basic understanding of the process of coolant heat transfer inside an engine is an indispensable prerequisite to devise an infallible cooling strategy. Coolant flow and its heat transfer affect the cooling efficiency, thermal load of heated components, and thermal efficiency of a diesel engine. An efficient approach to studying cooling system for diesel engine is a 3D computational fluid dynami...
