摘　　要：研究了单个典型通道组件堆外水力试验边界的设计方法,分析认为只有保证试验模型与原型间隙稳定段流道压降相同、流量相等才能确保试验模型等效反映原型。基于这种等效设计思路进行推导计算,设计得到了单个组件水力试验筒体,并利用数值模拟和关系式两种方法分别进行了验证,验证结果表明:等效设计方法是正确可靠的。A design method of out-of-pile hydraulic test boundary for a single core assembly is studied.It is concluded that only by ensuring the same pressure-drop and the equal flow rate in the gap flow channel can the experinment model be equivalent to the prototype.Based on this equivalent idea,a hydraulic experimental barrel for a single core assembly is designed and calculated by numerical calculation and the empirical formula.The results show that the equivalent design method is reliable and correct.
