We present a thermodynamically consistent discrete fluid particle model for the simulation of a recently proposed set of hydrodynamic equations for a phase separating van der Waals fluid mixture [P. Español and C.A.P. Thieulot, J. Chem. Phys. 118, 9109 (2003)]. The discrete model is formulated by following a discretization procedure given by the smoothed particle hydrodynamics (SPH) method within the thermodynamically consistent general equation for the nonequilibrium reversible-irreversible coupling (GENERIC) framework. Each fluid particle carries information on the mass, momentum, energy, and the mass fraction of the different components. The discrete model allows one to simulate nonisothermal dynamic evolution of phase separating fluids with surface tension effects while respecting the first and second laws of thermodynamics exactly.
我们提出了一种热力学一致的离散流体粒子模型，用于模拟最近针对相分离范德瓦尔斯流体混合物提出的一组流体动力学方程[P. Español和C.A.P. Thieulot，《化学物理杂志》118, 9109 (2003)]。该离散模型是通过遵循非平衡可逆-不可逆耦合（GENERIC）框架内的热力学一致通用方程中的光滑粒子流体动力学（SPH）方法给出的离散化过程来制定的。每个流体粒子携带有关不同组分的质量、动量、能量和质量分数的信息。该离散模型允许人们在精确遵守热力学第一和第二定律的同时，模拟具有表面张力效应的相分离流体的非等温动态演化。
