We first consider this minimum velocity for horizontal flow, the saltation velocity.
首先討論在水平流動時的最低速度,即沉積速度。 -
The hydraulic gradients of settling slurry flow transported in three kinds of moving states, i. e. suspension, saltation, or partially suspension were investigated, based on analyzing the changes of solid particles and water in momentum, velocity and their mass related to momentum exchanging over the acceleration period of the solid particles
從固體顆粒加速期間清水與固體顆粒的速度變化、動量傳遞、相關質量等基本問題分析入手,研究了沉降性漿體在水平管道內流動時其固體顆粒在3種流動狀態下的水力坡度,提出了沉降性漿體在水平管道內流動的機理模型,進而用該模型對一些輸送條件下的沉降性漿體的水力坡度進行了計算。
