摘要：

Based on the incompressible smoothed particle hydrodynamics (ISPH) method, a program was developed to simulate the non-Newtonian fluid flow in the mixing section of a single screw extruder. The transverse flow in the extruder is mimicked by one 2-D lid-driven cavity flow. The mirror particles are used to treat boundary. The power-law model is used to calculate the viscosity of the fluid. The shear-thinning, the shear-thickening and Newtonian fluid in the single screw extruder are simulated and deeply analyzed. Through comparing the velocity profile along the centre of screw extruder with the theoretical solution, this method has been proven to be accurate and effective. It laid the foundation for the simulating of the more complex 3-D model.
