Peristaltic motion of a non-Newtonian, incompressible power law fluid with suspension of small particles in a two-dimensional channel is analyzed. A perturbation method has been employed to obtain the solution of the problem under the long wavelength approximation. The formation and growth of trapping zone are explained for variations in amplitude ratio and volume flow rate. The phenomenon of reflux has been studied. The behaviour of the axial velocity of fluid and solid particles has been discussed. The speed of the suspended particles is observed to be less than that of the fluid particles.
分析了二维通道中具有小颗粒悬浮的非牛顿不可压缩幂律流体的蠕动运动。采用摄动方法在长波长近似下获得问题的解。针对振幅比和体积流量的变化解释了捕获区的形成和生长。研究了回流现象。讨论了流体和固体颗粒轴向速度的行为。观察到悬浮颗粒的速度小于流体颗粒的速度。
