摘   要：We develop a fictitious domain method with Distributed Lagrange Multipliers for simulating 2D unsteady shear-thinning non-newtonian incompressible flow in a single-screw and twin-screw extruder. A least-squares/finite element fictitious domain method is presented in a system which modeling the motion of the contact line separating two immiscible incompressible viscous fluids near a solid wall. Similarly, we discuss a least squares/fictitious domain method for incompressible viscous ow around obstacles with Navier slip boundary condition. Finally,  the new fictious domain method is also developed for direct simulation of fluid particle motion with Navier slip boundary condition at the fluid particle interface.
