实数编码晶格气方法由Malevanets（1997）提出。在这个新的格子气模型中，粒子具有连续的速度分布，在平衡态下服从Maxwell-Boltzmann分布。此外，冲突和流方案不依赖于显式的晶格结构。扩展到三维计算在概念上和实际上都变得简单。通过引入有色粒子及其相互作用，我们将这一创新模型扩展到不混溶二元流体的建模。基准计算表明，在二维和三维空间中，均满足拉普拉斯定律。成功地模拟了实际不互溶二元流体中发生的现象。该模型工作稳定，并已观察到与著名的液滴行为的定性协议。
The real-coded lattice gas method was proposed by Malevanets (1997). In this new lattice gas model, particles have continuous velocity distributions, which would yield to Maxwell–Boltzmann distribution in the equilibrium state. Furthermore, collision and streaming schemes do not depend on the explicit lattice structure. Extension to the three-dimensional calculation becomes straightforward both conceptually and practically. We extended this innovative model to the modeling of immiscible binary fluids by introducing colored particles and their interactions. Benchmark calculations show that Laplace law is satisfied in both 2D and 3D spaces. Simulations of phenomena occurring in the realistic immiscible binary fluids were carried out successfully. The model worked stably, and the qualitative agreement with the well-known droplet behavior has been observed.
