Research on design software of long-distance steam pipe network
摘要：
从工程应用角度出发，考虑蒸汽管道水力热力特性的相互影响和过热蒸汽热力参数的变化，建立了长距离蒸汽管网的水力热力耦合计算模型。以Qt5.10.0为开发平台，耦合IAPWS-IF97计算公式开发了蒸汽管网设计计算软件，介绍了程序设计流程、软件的管网绘制及设计计算模块、散热计算模块和水蒸气参数计算模块。利用该软件对某实际工程长距离蒸汽管网进行了设计计算。
Abstract：
Based on the perspective of engineering application, the hydraulic and thermal coupling calculation model of long-distance steam pipe network is established by considering the mutual influence of the hydraulic and thermal characteristics of the steam pipeline and the change of superheated steam thermal parameters. Taking the Qt5.10.0 as the development platform and coupling the IAPWS-IF97 calculation formula, the design and calculation software of steam pipe network is developed. The program design flow, the pipe network drawing and design calculation module, the heat dissipation calculation module and the water vapor parameter calculation module of the software are presented. The software is used to design and calculate the long-distance steam pipe network of a practical project.
