流化床反应器在化工、石油、冶金等行业有着广泛应用，反应器中常常存着各种各样的内构件，如布风板、筛板、导流挡板等，这些结构一般对气固流化床的流化状态有着显著影响。传统CFD技术对于薄片结构往往在网格处理时存在一定难度，且会造成整体计算网格数量的增多，极大地影响模拟仿真效率。

基于CPFD(Computational Particle Fluid Dynamics)技术开发的Barracuda是一款致力于工业级流态化及化学反应模拟的商业软件包，以其快速的仿真建模方法、高效稳定的多相流耦合求解器、便捷的化学反应建模方法、工业级的颗粒模拟数量等优点在水泥行业有着很好地应用。相比于传统CFD软件，Barracuda能够在更短的时间内实现工业设备的模拟分析，满足工业仿真需求。

Summary

At PSRI, we use modeling to support and expand our experimental efforts and vice versa. CPFD’s Barracuda Virtual Reactor is an essential part of that research process. PSRI performs experiments on a large scale with circulating fluidized beds up to 3-ft diameter riser, 90-ft in height, and fluidized beds ranging from 12-inch to 7-ft in diameter. With experiments on such a large scale, it would not be cost-effective to proceed with a research program without first exploring our options using modeling. Similarly, modeling is an integral part of our analysis process. It helps us better understand what we are measuring and bridge that gap of what we can and cannot do in the lab. In short, modeling is used as our hypothesis, and as our analysis tool driving our scientific method. Barracuda Virtual Reactor is an integral part of this approach. From the redesign of the PSRI attrition jet cup to understanding gas bypassing to reducing the number of experiments with our stripper study, Barracuda Virtual Reactor has streamlined our efforts while enriching our understanding and enhancing our technology.
