| Summary: | In this thesis, we use the particle method of Smoothed Particle Hydrodynamics
(SPH) to simulate Couette-Poiseuille
ow of Bingham plastic
uid. Couette-
Poiseuille
ow is a laminar
ow of viscous
uids within a gap between two parallel
plates caused by the dierence of pressure and plate movement relative to each
other. Moreover, Bingham plastic
uid is a kind of Non-Newtonian
uid which
behaves like a solid under the yield stress and
ows like viscous
uids when its
yield stress is exceeded. As the constitutive equation, we apply two models: dual-
viscosity and Papanastasiou model. Then, we analyze the velocity prole of the
uid for various values of yield stresses and plate's velocities. |
