采用拉格朗日方法,通过描述微粒的运动轨迹,研究了多分散悬浮固体微粒向孔道表面沉积的微观动力学特征,给出了五种不同沉积方式的判定条件,通过对流场的修正,得到了微粒液度的宏观变化与局部沉积特性之间的关系。
Using Lagrange method, the microscopic kinetic characteristics of polydisperse suspending solid particles to the pore surface are studied by describing the motion trajectory of the particles. Five different deposition methods are given to determine the microcosmic dynamics. Through the correction of the flow field, The relationship between the macroscopic changes of the particle liquidity and the local deposition characteristics was obtained.
