摘要/Abstract

摘要： 在局部模型上, 对阀门后廊道不同的突扩方向、突扩比、突扩起点的阀门段阻力系数ξvn进行了研究, 并建立了适用范围较大的经验计算式. 可供教学、科研及工程设计人员参考.

关键词: 阀门段阻力系数, 突扩体型, 突扩比

Abstract: Based on local model experiment, the resistance coefficient ξvn on valve section under the variant sudden enlargement direction、ratio、 initial point behind the valve in flush gallery is studied, and we establish a widely applying range emprical calculated formula, which can be referred to by people engaged in education, research and project designing.
