Two-Phase Flow Simulation Using the Lattice Boltzmann Method (LBM)

When simulating two-phase flow using the Lattice Boltzmann Method (LBM), we can model complex phenomena by tracking the motion of distinct fluid particles. This approach not only helps in understanding fundamental characteristics of two-phase flows but also enables the investigation of various fluid dynamics problems. Key implementations typically involve defining separate distribution functions for each phase, implementing interaction forces through potential models like the Shan-Chen pseudo-potential, and handling phase interfaces with appropriate boundary conditions. The LBM achieves an optimal balance between computational efficiency and simulation accuracy, making it widely applicable in engineering design and scientific research. Code implementation often involves iterative collision-streaming steps with density and velocity calculations derived from particle distribution functions, allowing effective simulation of diverse two-phase flow behaviors for deeper insights into their underlying mechanics.
