摘要: The purpose of this study is to establish the analysis method for prediction temperature during cryogenic heat treatment. Experimental treatment conducted observe phenomena such as boiling fluid, ice layer on material surface and measure distribution Al6061 tube. CFD considering observed in experiment performed predict convection transfer coefficient at each stage treatment, which fluid considered multi-phase condition vapour liquid. formation tube also modeled between fluid. predicted results are good agreement with experimental ones. From results, it shown that can
