以下为句子列表:
英文: According to non-Newtonian fluid mechanics theory and mathematical method, conbined with plunger moving property, the hypothesize fluid is imcompressive, hydraulic radius of flow of liquid in crevice is very little, and it is laminar flow, the flow is tre
中文: 运用非牛顿流体力学理论和数理方法,结合抽油泵柱塞运动特点,假设液体为不可压缩的,液体在缝隙中流动的水力半径很小,呈层流流动,柱塞在每一位置的瞬间,流动做定常流处理,建立了泵筒与柱塞同心和偏心两种情况下运动方程和边界条件,引入无量纲坐标、无量纲速度和柱塞与泵筒偏心配合时的缝隙高度,并给出缝隙流流速、流量的解析解。
