摘要:: 基于节点的管网分析方法不适用于含有喷管、折流管的特殊管网,作者用拆分技术将含有喷管、折流管的特殊管网转化为普通管网,能够采用节点法进行计算.在进一步的冷却分析中,由于较先进的冷却分析模型将冷却剂温度当常量处理,致使管网上的温度结果不能直接使用,必须进行修正和均化处理,提出了管道连入度、连出度的概念,据此能够沿着冷却剂流动的方向,对管网的各个管段进行修正和均化处理,取得较好效果.

Abstract:: The node-based pipe network analysis method is not suitable for special pipe networks containing nozzles and baffles, and the authors use splitting technology to convert the special pipe networks containing nozzles and baffles into ordinary pipe networks, which can be calculated by the nodal method. In further cooling analysis, because the more advanced cooling analysis model treats the coolant temperature as a constant, the temperature results on the pipe network cannot be used directly, and must be corrected and homogenized, and the concept of pipeline in-access and out-of-line degree is proposed, according to which each pipe section of the pipe network can be corrected and homogenized along the direction of coolant flow, and good results can be achieved.
