Numerical Simulation of Sudden Contraction Flow for Viscoelastic Fluids with the Lattice Boltzmann Method
2017
Proceedings of the 3rd Annual International Conference on Mechanics and Mechanical Engineering (MME 2016)
unpublished
In this paper, based on the lattice Boltzmann method (LBM) and the Oldroyd-B model, the decoupled solving method for the incompressible Navier-Stokes equation and advectiondiffusion constitutive equation and the boundary processing formats are given. The flow of viscoelastic fluid in the planar 3:1 contraction channel is simulated. For different Reynolds numbers Re, Weissenberg numbers Wi and viscosity s, the streamline patterns, the positions of vortex center and the length of vortex are
