摘要: A lattice-Boltzmann-equation method for nonideal gases augmented by the pressure evolution equation is proposed to simulate isothermal two-phase fluid flow with phase change. The derived taking time derivative of state gases. Unlike previous methods that use update pressure, field evolved using equation. new approach has two advantages. First, it can avoid spurious fluctuations at interfaces develop owing state, thus improving numerical stability method. Second, permits compressibility when change occurs due pressurization and depressurization. applied an process. result in excellent agreement analytical solution.
