An Axisymmetric Lattice Boltzmann Model for Simulation of Taylor Couette Flows between Two Concentric Cylinders
Recently, Halliday et al. presented an idea by inserting the “source” terms into the two-dimensional (2D) lattice Boltzmann equation (LBE) so that the emergent dynamics of the lattice fluid can be transformed into the cylindrical polar system. This paper further extends the idea of Halliday et al. to include the effect of azimuthal rotation. The terms related to the azimuthal effect are conside...
متن کاملModified lattice Boltzmann model for axisymmetric flows.
A modified lattice Boltzmann model based on the two-dimensional, nine-velocity lattice-Bhatnagar-Gross-Krook fluid is presented for axisymmetric flows. A spatially and temporally varying source term is incorporated into the evolution equation for the momentum distribution function on a two-dimensional Cartesian lattice. The precise form of the source term is derived through a Chapman-Enskog ana...
متن کاملDeformation and Breakup of Drops in Axisymmetric Flows and Comparisons with the Taylor Analogy Breakup Model
The Taylor analogy breakup (TAB) model is used for the prediction of drop deformation and drop breakup in spray simulations conducted with CFD codes. This model assumes that a spherical droplet moving in a gas stream behaves like a forced, damped harmonic oscillator in which the forcing term is given by the aerodynamic drag, the damping is due to the liquid viscosity and the restoring force is ...
متن کاملInterface Tracking for Axisymmetric Flows
A front tracking method for inviscid gas dynamics is presented. The key constructions and algorithms used in the code are described and the interrelations between shock capturing, interface dynamics, computational geometry, grid construction, and parallelism are discussed for the code as a whole. Validation is carried out by comparing the single mode bubble velocity for Rayleigh–Taylor instabil...
متن کاملA Mathematical Model for Flood Protection
Many regions in the world are protected against flooding by a dike, which may be either natural or artificial. We deal with a model for finding the optimal heights of such a dike in the future. It minimizes the sum of the investments costs for upgrading the dike in the future and the expected costs due to flooding. The model is highly nonlinear, nonconvex, and infinite-dimensional. Despite this...
