Simulation of Micro-Channel and Micro-Orifice Flow Using Lattice Boltzmann Method with Langmuir Slip Model
Because of its kinetic nature and computational advantages, the Lattice Boltzmann method (LBM) has been well accepted as a useful tool to simulate micro-scale flows. The slip boundary model plays a crucial role in the accuracy of solutions for micro-channel flow simulations. The most used slip boundary condition is the Maxwell slip model. The results of Maxwell slip model are affected by the ac...

متن کاملSPE 135506 Pore Scale Simulation of Flow in Porous Media Using Lattice-Boltzmann Computer Simulations
We describe the ongoing development of lattice-Boltzmann (LB) computer simulation codes to study flow in porous media at the pore scale. LB simulations have evolved over the past decade and are now used as a tool to calculate both singleand multi-phase flow properties directly at the pore scale using X-ray Micro Tomography (XMT) pore space images. We will review the development of our codes to ...
متن کاملPore-scale lattice Boltzmann simulation of laminar and turbulent flow through a sphere pack
The lattice Boltzmann method can be used to simulate flow through porous media with full geometrical resolution. With such a direct numerical simulation, it becomes possible to study fundamental effects which are difficult to assess either by developing macroscopic mathematical models or experiments. We first evaluate the lattice Boltzmann method with various boundary handling of the solid-wall...
متن کاملInvestigation of pore-scale random porous media using lattice boltzmann method
The permeability and tortuosity of pore-scale two and three-dimensional random porous media were calculated using the Lattice Boltzmann method (LBM). Effects of geometrical parameters of medium on permeability and tortuosity were investigated as well. Two major models of random porous media were reconstructed by computerized tomography method: Randomly distributed rectangular obstacles in a uni...
