Abstract:Numerical simulation of nonideal fluids is one of the most successful applications of the lattice Boltzmann method. The Chapman–Enskog (C–E) analysis reveals that the pressure tensor in the chemical-potential lattice Boltzmann model deviates from the standard one, and consequently, the surface tension cannot be effectively adjusted by the coefficient. In this paper, an additional term is constructed to modify the pressure tensor, while a scaling factor is utilized to prevent the expansion of the phase interfac… Show more
