论文摘要
我们提出了一种新颖的方法来进行动力学理论建模,以实现其相应状态方程式提供的通用,真实气体的模拟。该模型基于质量,动量和能量保护,与晶格玻尔兹曼模型不同,可以模拟超级和亚临界状态中表现出液体蒸气相变的流体。在这个新的动力学理论中,可以通过重新缩放离散的粒子速度来引入一个任意状态的方程式。与真实总和热力学相关的不同基准表明,所提出的方案可以处理广泛的可压缩多相流。
We present a novel approach to kinetic theory modeling enabling the simulation of a generic, real gas presented by its corresponding equation of state. The model is based on mass, momentum and energy conservation, and unlike the lattice Boltzmann models enables simulations of fluids exhibiting a liquid-vapor phase transition in both super- and subcritical states. In this new kinetic theory,an arbitrary equation of state can be introduced through rescaling the discrete particle velocities.Different benchmarks associated with real-gas thermodynamics illustrate that the proposed scheme can handle a wide range of compressible multiphase flows.
