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

这个小企业创新研究的第一阶段项目是为多相和反应的计算流体动力学（CFD）开发晶格玻尔兹曼方法（LBM）。拟议的工作将开发基于相场模型的界面捕获LBM -这是当前研究的前沿领域。LBM代码将使用相场方法开发和验证相变化，具有大范围的相密度对比，以及有或没有反应的传质。如果取得成功，该计划将为工业带来各种多相反应器和分离设备的高保真模拟，从而节省大量的时间和金钱，用于设计和扩大规模。拟议发展的影响将远远超出化学行业，例如广泛应用于电力系统和环境模拟。

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.
