SBIR Phase I: Lattice Boltzmann Method for Multiphase Reacting Flows with Chemical Industry Applications

这个小型企业创新研究第一阶段项目是为了开发用于多相和反应的计算流体力学(CFD)的格子Boltzmann方法(LBM)。这项拟议的工作将开发基于相场模型的界面捕获的LBM-这是当前研究的前沿领域。LBM程序将用相场方法开发和验证，用于相变，具有大范围的相密度对比度和传质，有反应和没有反应。拟议中的开发如果成功，将在行业范围内实现对各种多相反应器和分离设备的高保真模拟，从而节省大量设计和扩大规模的时间和资金。拟议的发展将产生远远超出化学部门的影响，例如在电力系统和环境模拟方面的广泛应用。

This Small Business Innovation Research Phase I project is for development of lattice Boltzmann methods (LBM) for computational fluid dynamics (CFD) of multiphase and reaction. The proposed work will develop LBM for interface capturing based on phase-field models - an area at the cutting edge of current research. The LBM codes will be developed and validated with phasefield approaches for phase change, with a wide range of phase density contrasts, and mass transfer, with and without reactions. The proposed developments, if successful, will bring within industry's reach high-fidelity simulations of a variety of multiphase reactors and separations equipment saving considerable time and money for design and scale up. The proposed developments would have impact far beyond the chemical sector, e.g. with wide applications to power systems and environmental simulations.
