Numerical Simulation of Bubbles under an Inclined Plane: Application to Aluminum Electrolysis
نویسندگان
چکیده
The numerical investigation of large bubbles rising under an inclined plane is presented. A numerical method for the simulation of fluid flows with complex free surfaces is presented, in which the liquid is assumed to be Newtonian, while gas bubbles are assumed to be compressible. A volume-of-fluid method is used to track the liquid domain. A time splitting algorithm allows to decouple the advection and diffusion operators, the compressibility effects in the gas, and the surface tension effects. Finite element techniques are coupled with a characteristics method with a two grids method. Numerical simulations are in excellent agreement with experimental data.

Simulation of Foaming and Deformation for Composite Aluminum Foams
In this study, at the first stage, the rupture criterion of bubbles wall in Aluminum metal foam liquid was investigated by using Lattice Boltzmann. The two phases modeling were accomplished by using a modified Shan-Chen model. This model was run for several bubbles in A356+3wt.%SiC melt system. Then, bubbles morphologies (virtual metallographic) for A356+3wt.%SiC foams were simulated. Results s...

An analytical model is developed to study the viscoelastic micropolar fluid convection from an inclined plate as a simulation of electro-conductive polymer materials processing with nonlinear temperature. Jeffery’s viscoelastic model is deployed to describe the non-Newtonian characteristics of the fluid and provides a good approximation for polymers. Micro-structural is one of the characteristi...

This work concerns the peristaltic flow of a Williamson fluid model in an inclined asymmetric channel under combined effects of heat and mass transfer. The governing nonlinear partial differential equations are simplified under the lubrication approach and then solved analytically and numerically. The analytical results are computed with the help of regular perturbation and the numerical re...

Occurrence of laminar separation bubbles on solid walls of an elliptic cylinder has been simulated using a recently developed transitional model for boundary layer flows. Computational method is based on the solution of the Reynolds averaged Navier-Stokes (RANS) equations and the eddy-viscosity concept. Transitional model tries to simulate streamwise fluctuations, induced by freestream turbulen...
