纤维悬浮液湍流射流数学模型的研究

Numerical Model on the Jet Flow of Pulp Suspension

纸浆离开流浆箱喷嘴的流动是一种两相平面湍流射流运动，其流动状态对上网成形的质量具有重要的影响．本文从两相流体流动出发，对纸浆的这种射流流动机理进行了探讨，并推导了表示其流动状态的微分方程组．

The pulp flow becomes a kind of jet flow while through the nozzle of headbox,and the character of this jet flow plays a critical role on the forming quality.By means of the two phase flow mechanism,the principle of pulp jet flow is analyzed in this paper,and the primary differential equations is also founded.
