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。

      Barracuda Virtual Reactor, powered by NVIDIA GPUs, enables sustainability technologies that are changing our planet for the better. This two-part industry case study provides an overview of a novel waste-to-fuels technology that is sustainable, versatile, and economically competitive with fossil fuels. In the first part of the presentation, we provide a summary of ThermoChem Recovery International, USA’s digitalization journey with CPFD Software’s Virtual Reactor culminating in the commercial conversion of municipal solid waste to jet fuel. In the second half, we overlay our parallel development and acceleration path resulting in speed-ups of over 600x over the project period. Ongoing R&D results including multi-GPU computing are presented. Lastly, the practical meaning of the speed-ups is discussed; previously intractable problems are now solved in industrially relevant time scales. Extensions of the new multi-GPU technology to other sustainability applications are highlighted。
