Abstract
다양한 산업 공정에서 배관은 각 단위공정 사이의 연결 매개체의 역할을 하며, 내부의 유동에 있어 필수적인 장치이다. 따라서 배관의 최적설계는 안전과 비용의 측면에서 매우 중요한 문제이며, 설계 시 필수적인 사항은 배관 내 압력강하 및 유속, 배관 지름 등을 결정하는 일이다. 본 연구에서는 배관 지름 및 유속이 정해졌을 때 발생하는 압력강하, 배관의 압력강하 및 유속이 정해졌을 때의 배관 지름, 배관 지름 및 압력강하가 정해졌을 때의 유속을 결정하는 소프트웨어를 개발하였다. 배관 내 유동을 단일 상 흐름, 균질 2 상 유동, 분리 2 상 유동으로 구분하였으며 이에 따라 적절한 계산 모델을 적용하였다. 파이프의 재질 및 상대 거칠기, 유체의 물성치, 마찰계수의 계산을 위한 시스템 라이브러리를 구축하여 사용자의 입력을 최소화하였다. 배관 재질에 따른 가격 라이브러리를 구축하여 단위 길이당 배관 투자 비용의 산출을 가능하도록 구성하였다. 이러한 모든 기능은 사용자 편의를 위한 그래픽 사용자 인터페이스를 이용한 통합 환경에서 구현할 수 있으며, C# 언어를 개발 언어로 사용하였다. 소프트웨어의 정확도를 문헌 자료와 실 수행 과제의 예제를 통하여 검증하였으며 단일 상의 경우 1% 미만, 2 상의 경우 최고 8.8% 정도의 차이를 보였으며, 이에 따라 개발된 소프트웨어가 실제 공정의 계산에 유용하게 쓰일 수 있음을 알 수 있었다.
In various industrial processes, piping serves as a link between unit processes and is an essential installation for internal flow. Therefore, the optimum design of the piping system is very important in terms of safety and cost, which requires the estimation of the pressure drop, flow rate, pipe size, etc. in the piping system. In this study, we developed a software that determines pressure drop, flow rate, and pipe size when any two of these design variables are known. We categorized the flows into single phase, homogeneous two phase, and separated two phase flows, and applied suitable calculation models accordingly. We also constructed a system library for the calculation of the pipe material, relative roughness, fluid property, and friction coefficients to minimize user input. We further created a costing library according to the piping material for the calculation of the investment cost of the pipe per unit length. We implemented all these functions in an integrated environment using a graphical user interface for user convenience, and C # programming language. Finally, we verified the accuracy of the software using literature data and examples from an industrial process with obtained deviations of 1% and 8.8% for the single phase and two-phase models.
