英文摘要: |
In view of the influence of gas on the valve flow capacity in the use of angle regulating valve, the FLUENT software was used for numerical
simulation. The velocity and flow rate of the angle regulator in the gas liquid two phase flow were analyzed by using the Euler multiphase flow model to obtain the influence of the inlet
gas volume fraction and the valve body structure on the flow coefficient. The results show the great influence of volume fraction of the inlet gas on the flow coefficient which can be
improved by changing the sealing angle and flow angle. The improved valve has better circulation capacity and provides a reference for the improvement of similar valves. |
