The unstructured lattice Boltzmann method for non-Newtonian flows
Non-Newtonian models with shear-thinning viscosity are commonly used to solve a variety of complex flow problems. A new finite-volume discretization based upon an unstructured grid is used to integrate the differential form of the lattice Boltzmann equation with a shear-dependent viscosity, using a cell-vertex finite-volume technique. The unknown fields are placed at the nodes of the mesh and e...

Non-Newtonian models with shear-thinning viscosity are commonly used to solve a variety of complex flow problems. A new finite-volume discretisation based upon an unstructured grid is used to integrate the differential form of the Lattice Boltzmann equation (ULBE) with a shear-dependent viscosity, using a cell-vertex finite-volume technique. The unknown fields are placed at the nodes of the mes...
متن کاملLattice Boltzmann Method for Fluid Flows
We present an overview of the lattice Boltzmann method (LBM), a parallel and efficient algorithm for simulating single-phase and multiphase fluid flows and for incorporating additional physical complexities. The LBM is especially useful for modeling complicated boundary conditions and multiphase interfaces. Recent extensions of this method are described, including simulations of fluid turbulenc...
متن کاملIncompressible Non-Newtonian Fluid Flows
A non-Newtonian fluid is a fluid whose flow properties differ in many ways from those of Newtonian fluids. Most commonly the viscosity of non-Newtonian fluids is not independent of shear rate or shear rate history. In practice, many fluid materials exhibits non-Newtonian fluid behavior such as: salt solutions, molten, ketchup, custard, toothpaste, starch suspensions, paint, blood, and shampoo e...
متن کاملConstruction of a non-Newtonian fluid model based on the finite difference lattice Boltzmann method
A model of the lattice Boltzmann method for non-Newtonian fluids was constructed. The shear stress of purely viscous but non-elastic non-Newtonian fluid is a function of shear rate only. For the power-law model, only two constant parameters can cover shear-thinning and shear-thickening fluids. Two power-law models are introduced to the finite difference lattice Boltzmann method. One is a model ...
