旋流器内单相流场压力降的研究

Study to Pressure Drop in Single Flow Field of Cyclone

根据牛顿第二定律运动表达式,充分考虑所选取流体微元表面特征,对旋流器内部压力场进行深入研究,推导出新的压力沿径向和轴向分布的数学表达式,并对理论结果进行讨论分析,得到压力降的数学表达式,并最终确定影响旋流器压力降的主要因素。

According to motion expression of Newton Second Law and fully considering the surface characteristic of selected mini fluid body ,the paper deeply studied the pressure field inside cyclone and deduced the pressure distribution expression along radial direction and axial direction,carried on analysis to the theory result and deduced the expression of pressure drop,finally determined major factors that affected the pressure drop of cyclone.
