Numerical Simulation for Ⅰ-Ⅱ Types of Distribution Header Throttle Structure in CEFR

In the simulation of distribution header throttle structure, using the computational fluid dynamic code-CFX, compared with experiment, the reasons of error were discussed and the reliability of this simulation was proved. Same types of calculations were checked, and the relationship between CFD and experiment was described. The results provide theoretic base and reference for CFD.
