【摘要】 本文对气体-纤维两维粘性定常流动的计算采用了网格中的质点源(PSI)模型方法。它包括以网格中的源项形式来计算气体相的质量守恒方程与动量方程。以球链模型代替纤维,网格中的动量源项是由计算网格中的纤维对气体的作用力的冲量而决定的。对典型流场中的气体-纤维流动作了数值计算,其中之一与 Bangert 和Sagdeo 的实验作了比较。更多还原

【Abstract】 In this paper the PSI-CELL model which includes the calculation of the mass con-servation equation and the momentum equations with source terms in cell is adopted forthe gas-fiber two dimensional steady viscous,flow.The ball-chain model taking theplace of fiber in this paper,the momentum source in cell is decided by calculating theimpulse of the force of fiber to gas in the cell.The numerical solutions to gas-fiberfiow in some typical flowing fields have been made,and one of those has been compar-ed with the experimental results obtained by Bangert and Sagdeo.更多还原
