This Small Business Innovative Research Phase I project will develop an engineering design level simulation tool for non-Newtonian flow systems, such as polymers and suspensions used in advanced materials engineering and process design. Recently developed innovative modeling of rheological properties at a mesoscopic level, using a rate-of-strain dependent relaxation time in the lattice Boltzmann method (LBM), will be used. Validation studies will include quantitative analysis of "spurt" in pressure-driven flow and persistent oscillations in piston-driven flow followed by a qualitative pilot study of polymeric flow in a complex geometrical industrial prototype device. This project will produce design tools that are urgently needed to overcome physical and/or engineering limits in various manufacturing and processing industries, Potential applications include coating and fiber spinning, design and production of new processes and materials for filled and unfilled silicones, diesel powerplant and emissions, injection molding, environmentally benign processes, drag reduction in naval engineering, and ant-icing aircraft sprays.

这个小型企业创新研究阶段I项目将为非牛顿流系统（例如高级材料工程和过程设计中使用的聚合物和悬架）开发工程设计水平模拟工具。最近，将使用使用晶格Boltzmann方法（LBM）中的率依赖性的松弛时间（LBM）在介质水平上开发的流变特性创新建模。验证研究将包括对压力驱动流动中“喷射”的定量分析以及活塞驱动流中的持续振荡，然后在复杂的几何工业原型设备中对聚合物流的定性试验研究。该项目将生产出迫切需要的设计工具，以克服各种制造和加工行业的物理和/或工程限制，潜在的应用包括涂料和纤维旋转，新工艺的设计和生产，用于填充和未填充的硅胶，柴油动力和排放，柴油机和排放，柴油机和排放，环境成型，环境良性造型，降低海军工程和蚂蚁式斗式斗式派对派对，并降低了斗式斗式派对派对。
