摘要 本文采用数值模拟的方法计算了稠密气固两相流中单个颗粒所受到的气动力.通过与实验数据的比较分析了数值计算的准确性.对于空间均匀排列的多颗粒分布形式计算了其中单个颗粒所受到的气动力随颗粒空隙率(颗粒浓度)的变化规律. Drag force on an isolated particle has been investigated computationally. The accuracy of calculation has been examined through comparison with the available experimental and theoretical results. For the uniform spacial arrangement of particles, the effect of particle volume fraction on drag force has been calculated.
