摘　　要：该文采用一种直接数值模拟方法的流体体积分率法来模拟射流流化床反应器内的流动特性,模拟结果表明:射流流化床中的鼓泡特性可以用流体体积分率法来模拟,计算得到的气泡大小增长速率、不同高度上时间平均的孔隙率分布、时间平均的全局孔隙率分布等参数与文献中报导的实验结果相吻合。In this paper, a direct numerical simulation technique, volume of fluid method, is used to the hydrodynamics of a jetting fluidized bed. It was shown that the experimentally measured hydrodynamics, including bubble growth rate, time-averaged voidage distribution at different heights and averaged global voidage distribution, are reproduced reasonably well by volume of fluid method. study bed time -averaged global voidage distribution, are reproduced reasonably well by volume of fluid method.
