9305850 Gidaspow It is proposed to calibrate and extend the area of application of a numerical approach for three-dimensional, transient, fluidized bed simulation. Comparisons to experimental results in bubbly, gas-solid circulating, and three-phase fluidized beds will be performed. Validation tests for grid generation, constitutive relationships and limit flow patterns are planned. Reference experiments will performed in collaboration with another group at IIT to determine phase distributions and velocities by using a gamma-ray densitometer, a X-ray densitometer, and radioactive particle tracking. It is expected that more reliable, accurate, simulations for both gas-solid and three-phase fluidized systems will be available at the end of the project. Close collaborations with industry and national laboratories are also planned. The proposed computational approach will permit better design and scale-up of gas-solid and gas-solid-liquid fluidized beds used in chemical manufacturing, oil industry, and biotechnology.

本文提出了一种校正和扩展三维瞬态流化床数值模拟的应用领域的方法。将与气泡、气固循环和三相流化床的实验结果进行比较。规划了网格生成、本构关系和极限流型的验证测试。参考实验将与印度理工学院的另一个小组合作进行，通过使用伽马射线密度计、x射线密度计和放射性粒子跟踪来确定相分布和速度。预计在项目结束时，气固和三相流化系统的更可靠、更准确的模拟将可用。还计划与工业和国家实验室密切合作。所提出的计算方法将允许更好的设计和放大气固和气固液流化床用于化学制造，石油工业，和生物技术。
