【摘要】 荷电两相湍流存在着非均匀的空间电场与流场的耦合作用,以及荷电颗粒相与连续相流体的相间作用,是非常复杂的两相湍流运动。本文采用颗粒拟流体假设得到了荷电两相流动瞬时状态的方程组。根据雷诺时均方法,建立了荷电两相湍流的时间平均雷诺方程组,并对其中的脉动关联项进行了模拟。更多还原

【Abstract】 In charged two phase turbulent flow, there exists coupled action between space electric field and flow field, also exists phase interaction between charged particle phase and continuous phase, which makes the flow more complex. Based on the study of two-phase turbulence, equations for the instantaneous state of the electrostatic charged two-phase flow are obtained. According to Reynolds-average method, Reynolds-average equations for electrostatic charged two-phase flows are set up, and the model for electrostatic charged two-phase flow is presented by simulating the associated phase pulsation.更多还原
