| 摘 要： | 采用欧拉-欧拉双流体模型,颗粒动理学理论模拟颗粒相流动,对喷动床核反应器内的流体动力行为进行了数值模拟.模拟得到了喷动床核反应器内颗粒浓度标准方差、空隙率和颗粒速度分布.研究结果表明喷动床核反应器内颗粒浓度标准方差先逐渐增大至最大值后下降.分析了摩擦应力模型和倒锥体角度等影响因素对喷动床核反应器内的流体动力特性的影响.

| Abstract: | Hydrodynamics of fluid was numerically studied by means of an Eulerian-Eulerian two-fluid model in a spouted bed reactor.Nuclear fuel particles collisions were modeled by the kinetic theory of granular flow.The distribution of standard variance of particle concentration,porosity and velocity were obtained in the nuclear reactor.Numerical results indicate that the value of the standard variance of particle concentration firstly increased with the increasing mean particle concentration and after that decrease... |
