Lattice Boltzmann Models for Multicomponent Fluids

Abstract

This report results from a contract tasking Politehnica University of Timisoara as follows: The contractor will investigate the utility of Lattice Boltzmann methods in the modeling of complex (multicomponent) fluids. A two-dimensional Lattice Boltzmann model will be developed, the geometry of which is not related to the thermal velocities of fluid particles. Comprehensive testing and analysis of the model, as well as benchmarking against existing Lattice Boltzmann models will be accomplished. Initial testing will be accomplished by modeling one- component fluid flow in two spatial dimensions, followed by study of a two-component flow in two dimensions. Finally, interparticle interactions will be added to allow investigation of interfaces between multiphase fluids. Two specific physical problems investigated: the shape of a sessile drop on a horizontal surface subjected to a gravitational field, and the effect of surface tension on contact angle.
