Numerical simulation of single bubble rising in vertical and inclined square channel using lattice Boltzmann method

A lattice Boltzmann equation (LBE)model based on the Cahn–Hilliard diffuse interface approach is used to investigate thedynamics of a bubble rising in a vertical and inclined square channelwith large density and viscosity ratios. Deformation parameter D, film thickness d, and terminal velocity Ut of the bubble are interrelated quantities which depend on non-dimensional numbers such as Bond numb...

Numerical Study of Bubble Separation and Motion Using Lattice Boltzmann Method

In present paper acombination of three-dimensional isothermal and two-dimensional non-isothermal Lattice Boltzmann Method have been used to simulate the motion of bubble and effect of wetting properties of the surface on bubble separation. By combining these models, three-dimensional model has been used in two-dimension for decreasing the computational cost. Firstly, it has been ensured that th...

numerical simulation of fluid flow in random granular porous media using lattice boltzmann method

in this paper, fluid flow between two parallel flat plates that are partially filled with two-dimension porous media is investigated numerically using single relaxation time (srt) lattice boltzmann method (lbm) at pore scale. the considered obstacles are random, circular, rigid and granular with uniform diameters. single component and single-phase viscous newtonian fluid are considered as worki...

Numerical Simulation of Fluid Flow Past a Square Cylinder Using a Lattice Boltzmann Method

The method of lattice boltzmann equation(LBE) is a kinetic-based approach for fluid flow computations. In the last decade, minimal kinetic models, and primarily the LBE, have met with significant success in the simulation of complex hydrodynamic phenomena, ranging from slow flows in grossly irregular geometries to fully developed turbulence, to flow with dynamic phase transitions. In the presen...

Simulation on Cavitation Bubble Collapsing with Lattice Boltzmann Method

We consider a pressure (density) in a square flume solid boundaries and no-slip format condition formulation are introduced to investigate cavitation bubble for the two-dimensional lattice Boltzmann method (LBM). Using the coupling Carnahan-Starling equation of state (C-S EOS) and exact difference method (EDM) based on modified Shan-Chen model, the whole process of bubble collapse was observed ...
