摘要:The Immersed Boundary Method is used to model the walls bounding flows in straight channels. In this method a force source term is added to the Navier-Stokes equations, in order to guarantee the non-slipping boundary conditions at the channel walls. The Physical Virtual Model (PVM) is used to calculate the force field, which is a methodology that has been developed by the LTCM – FEMEC research group. This methodology employs the Navier-Stokes equations to compute the interfacial force presented in the flow. Results are presented for two types of flows: Poiseuille and Couette-Poiseuille. The results (velocity and friction coefficient) are compared with analytical results.
