U.S.-France Cooperative Research: CFD Simulation of Chemical Reactors: Development and Experimental Validation of Micromixing Models for Product Selectivity

这个为期三年的美法化学和热系统合作奖由爱荷华州立大学和法国鲁昂大学的研究人员和学生参加。罗德尼·O·福克斯和帕斯卡尔·多明戈分别领导着美国和法国的努力。计算流体动力学(CFD)宏观模型的液体相湍流反应流将被研究。这种模型有可能改进化工过程工业中的工艺设计。这项研究旨在探讨CFD模型在减少产品选择性差造成的污染和有毒副产品方面的应用。合作的重点是代码开发和验证，以及在爱荷华州平面喷气反应堆上进行的实验的详细模拟。美国研究小组将使用粒子图像测速仪和平面激光诱导荧光技术获得明确定义的反应堆几何结构的数据。这将得到法国研究小组对流动统计数据的直接数值模拟和大涡模拟的研究的补充，这些研究不容易用爱荷华州立大学研究小组使用的技术进行测量。该奖项代表美方向NSF和法国国家科学研究中心(CNRS)提出的联合建议。NSF将支付美国调查人员和学生的旅费和生活费。CNRS将支持法国与会者访问美国。这项合作将为液态化学反应器的CFD模型验证提供一组详细的数据。

0129064FoxThis three-year award for U.S.-France collaboration in chemical and thermal systems involves researchers and students at Iowa State University and the University of Rouen in France. Rodney O Fox and Pascale Domingo lead the US and French efforts respectively. Computational fluid dynamics (CFD) macroscopic models for liquid-phase turbulent reacting flows will be studied. Such models have potential for improving process design in the chemical process industry. The research addresses the utility of CFD models for reducing pollution and toxic byproducts caused by poor product selectivity. The collaboration's focus is code development and validation, and detailed simulations for experiments conducted on the Iowa State planar-jet reactor. The US research group will obtain data for a well-defined reactor geometry using particle-image velocimetry and planar laser-induced fluorescence. This will be complemented by the French group's studies of direct numerical simulations and large-eddy simulations of flow statistics that cannot easily be measured with the techniques used by the Iowa State group. This award represents the US side of joint proposals to the NSF and the French National Center for Scientific Research (CNRS). NSF will cover travel funds and living expenses of the US investigators and students. The CNRS will support visits to the US of the French participants. The collaboration will produce a set of detailed data for CFD model validation of liquid-phase chemical reactors.
