摘要
文章依据散体力学中Janssen理论对准流体的一种流动形态--侧向流进行受力分析,提出了加速度势的概念,对重力场下准流体质量流量公式进行了推导。通过重力场下准流体颗粒在不同容积大小的容器,流经不同孔径的泄流孔的流动试验,发现其流量呈现一定的规律,并且经过修正侧压力系数后的理论计算值与实际测算值相当接近。
The granular and fluid all have their own peculiar forms, otherwise the quasi-liquid that intervene has minority attention, besides that the theory study is not widely. The mechanicalI analysis of quasi-liquid in the pattern of lateral flow is made with the theory of Janssen, the concept of acceleration potential and the mass flow formulas of the auasi-liauid under I
