The transient, axisymmetric squeeze flow of the non-Newtonian shear thinning material between finite disks is studied numerically. The fluid between disks is assumed to follow the Carreau-Bird model. Two disks approach each other at a constant velocity while no-slip boundary condition is assumed. The time dependent simulation shows the effect of fluid nonlinearity, flow parameters and geometric aspect ratio on the flow dynamic and evolution of squeeze force. Also, some physical phenomena are shown and are explained at the edge of the disks and out of them. The conservation and momentum equations containing inertia effects are solved using moving mesh scheme and finite volume method. The SIMPLE algorithm is used to solve the pressure-velocity coupling.

两个平行盘之间挤压的非牛顿流体的数值研究

数值研究了非牛顿剪切稀化材料在有限圆盘之间的瞬态轴对称挤压流动。假设圆盘之间的流体遵循Carreau-Bird模型。在假定无滑移边界条件的情况下，两个圆盘以恒定的速度彼此接近。随时间变化的仿真显示了流体的非线性，流动参数和几何长宽比对流动动力和挤压力演变的影响。此外，在磁盘的边缘和边缘之外还显示并说明了一些物理现象。利用运动网格法和有限体积法求解了包含惯性效应的守恒方程和动量方程。SIMPLE算法用于求解压力-速度耦合。
