摘要
本文从气体动力学方程组出发,导出了明流泄水洞余幅部分的气流流速分布和气流量公式,进一步阐明了流速分布和流量以及影响它们因素之间的关系,并推出了洞内气流回流的必要条件。最后,应用冯家山水库明流溢洪洞的原型观测资料,验证了本文的数学模型。
Based on the air dynamic equations, this paper develops theoretical formulas for velocity distribution and flow rate of air flow, which is above the flowing water surface in non-pressure tunnel. And then, the relationship between the velocity distribution and flow rate and the related factors, is further clarified. Consequently,the necessary conditions of air-coming back in the tunnel is deduced. Finally, the mathematical models mentioned above are checked with the prototype data on the nonpressure flood-release tunnel of the Fengjia Mountain Hydroelectric Project. Thus, the method given out in this paper may be a reference for further research on air demand and project designing.
