Based on laboratory experiments and theoretical analysis, the equilibrium conditions of submerged clay mud, the phenomenon and mechanisms of efflux from orifice, distance of mud free jet, hydraulic jump of mud flow and local resistance of open channel mud flow are discussed in this paper. 通过试验和分析,本文讨论了泥浆的水下平衡、孔口出流及自由射流、泥浆水跃、断面突然变化处的流动以及局部阻力损失等问题。
At last, from dimensional analysis and experimental data, formulae of the submerged orifice discharge and its cofficient are derived. All these formulae are very convenient for calculation. 最后应用量纲和谐原理和模型试验资料得到了淹没孔流流量和流量系数的公式,用这些公式计算甚为简便。
