使用晶格玻尔兹曼模型模拟两种粘性、不混溶流体之间的渐进界面波，并将其与实验室水箱中产生的波进行比较，在实验室水箱中使用基于薄膜的粒子图像测速系统测量它们的速度。对两个相似的陡波的数值速度和实验速度进行了比较，发现结果非常吻合。结果还与一阶波浪理论进行了比较，在这两种情况下，它们预测的速度比理论高出 40%。 (C) 2002 年科学与医学 Elsevier SAS。版权所有。
Progressive interfacial waves are simulated between two viscous, immiscible fluids using a lattice Boltzmann model and compared to waves generated in a laboratory tank, where their velocities are measured using a film-based particle image velocimetry system. The numerical and experimental velocities are compared for two similar, steep waves and the results are found to be in good agreement. The results are also compared with a first order wave theory, in both cases they predict velocities up to 40% greater than the theory. (C) 2002 tditions scientifiques et medicales Elsevier SAS.
