Abstract:
Lattice Boltzmann method (LBM) is becoming an increasingly popular strategy for the simulation of multiphase process. Three approaches to multiphase flow have been developed up to now: the short-range forces based Shan and Chen LBM, which is simple but limited to a narrow range of parameters, the Color-field LBM, more versatile but also more complicated to implement, and finally the Free-energy LBM extremely polyvalent but needing even more complex code implementation. In this paper, we combined the two first methods, which are the most widely used the chemical engineering community. The resulting algorithm is more stable than the Shan and Chen method, and simpler than the Color-field. A few features of the method are a constant interface thickness, a linear relation between the interfacial tension and its parameter G, low spurious currents and total immiscibility enforced even at zero interfacial tension.
