摘　　要：本文分析了一无限大转动圆盘引起的稀薄气固两相流在无穷远处的流场渐近性质,提出了相应的级数解形式,对转盘表面有强吸气和弱注射的情况得到了一系列的高精度数值解。The asymptotic behavior of the flow produced in particle-suspension by an infinitely large rotating disk is analyzed. A corresponding series solution is presented. It is showed that this approach yields uniformly valid solution of high accuracy. For strong injection and the case in which there is a band of no particles near the disk, the series method fails.
