加速项 meaning in English
accelerated ejector
Examples
- In order to know the relationship between gas - content and pipeline ' s pressure drop , the thesis deduces the pressure drop calculating equations based on uniform flow pattern and separating flow pattern . the equations show that pressure drop is made up of three parts , that is , friction resistance effect , gas acceleration effect and the gravity effect . and the research has shown that the gas has little effect on pressure drop . in the horizontal pipeline , the resistance effect must be overmatched the acceleration effect
为探讨加入的气体对管道压力的影响，本文基于分相流和均相流两种模型分别推导了三相流管道的压降公式，表明无论是分相流模型，还是均匀流模型，管道内流体总的压降是由三项组成的，即摩擦项、加速项和重力项，并得出了加气对管压变化不大的结论，所以认为在水平管道中，要获得有效的减阻，则要使摩擦阻力分量的减小效应大于浆体加气的加速效应。
