标题： Thread-safe multiphase lattice Boltzmann model for droplet and bubble dynamics at high density and viscosity contrasts

摘要： 本研究提出了一种高阶、线程安全的格子玻尔兹曼方法（LBM）版本，结合了界面捕捉方程，基于保守型阿伦-卡恩方程，用于模拟具有高密度和粘度对比的不可压缩双组分系统。该方法利用了一种最近提出的针对共享内存架构优化的线程安全实现，并用于在多个测试案例中再现液滴和气泡的动力学，结果与实验和其他数值模拟结果一致。所提出的方法为具有高密度和粘度对比的真实流体系统的高性能计算模拟提供了有前景的机会，适用于环境、大气和气象流动等高级应用，甚至微流体和生物系统，特别是在基于GPU的架构上。 显示英文摘要

摘要： This study presents a high-order, thread-safe version of the lattice Boltzmann (LBM) method, incorporating an interface-capturing equation, based on the conservative Allen-Cahn equation, to simulate incompressible two-component systems with high-density and viscosity contrasts. The method utilizes a recently proposed thread-safe implementation optimized for shared memory architectures and it is employed to reproduce the dynamics of droplets and bubbles on several test cases with results in agreement with experiments and other numerical simulations from the literature. The proposed approach offers promising opportunities for high-performance computing simulations of realistic fluid systems with high-density and viscosity contrasts for advanced applications in environmental, atmospheric and meteorological flows, all the way down to microfluidic and biological systems, particularly on GPU-based architectures.
