论文摘要
我们概括为三个维度（3D），最近开发的改进的多组分伪能力晶格玻尔兹曼方法，并分析了其通过逼真的多孔介质模拟流量的适用性。该模型通过基准进行了验证和表征，我们通过模拟3D几何形状中不混溶的流体的位移来研究其性能。考虑了两个样品，即数字获得一包球，以及一个实验中获得的底栖二聚体砂岩样品。我们表明，通过这种模型，可以模拟逼真的粘度比，独立调整表面张力，最重要的是保留被困的流体的体积。我们还评估了模型在图形处理单元（GPU）上的计算性能，并提及实施的优化以提高计算速度并降低内存需求。
We generalize to three dimensions (3D) a recently developed improved multi-component pseudopotential lattice Boltzmann method and analyze its applicability to simulate flows through realistic porous media. The model is validated and characterized via benchmarks, and we investigate its performance by simulating the displacement of immiscible fluids in 3D geometries. Two samples are considered, namely, a pack of spheres obtained numerically, and a Bentheimer sandstone rock sample obtained experimentally. We show that, with this model it is possible to simulate realistic viscosity ratios, to tune surface tension independently and, most importantly, to preserve the volume of trapped fluid. We also evaluate the computational performance of the model on the Graphical Processing Unit (GPU) and mention the implemented optimizations to increase the computational speed and reduce the memory requirements.
