文摘

An improved iterative algorithm is proposed for solving near-critical fluid flows. Pressure–velocity coupling is treated through block-coupled method. Energy equation written in terms of the specific heat at constant pressure is used. The proposed algorithm has a better stability and can reduce the CPU time.
