چکیده

چکیده: گاز طبیعی به‌عنوان یک سرمایه ملی و منبع انرژی حیاتی، نیازمند حفظ و جلوگیری از اتلاف است. یکی از نقاط اصلی نشت گاز، بخش فشار پایین رگلاتورهای گاز شهری است که به دلیل تجمع ذرات معلق در دیافراگم و نقص عملکرد، موجب هدررفت انرژی و خسارت‌های اقتصادی می‌شود. این پژوهش با همکار شرکت گاز استان مازندران و با هدف کاهش نشت گاز، به شبیه‌سازی عددی، طراحی و ساخت نمونه‌های بهینه رگلاتور پرداخته است. در این تحقیق، اثر استفاده از موانع هدایت‌کننده جریان بر کاهش تجمع ذرات و بهبود توزیع جریان در بخش فشار پایین بررسی شده است. نتایج شبیه‌سازی نشان داد که مدل مانع منحنی با انحنای رو به ورودی می‌تواند مسیر جریان سیال را بهینه کرده و میزان نشت گاز از این محل را تا 100 درصد کاهش دهد. همچنین، نتایج آزمایش‌های عملی نشان داد که این مدل به‌طور مؤثری از تجمع ذرات در نشیمنگاه دیافراگم جلوگیری کرده و عملکرد پایدار رگلاتور را تضمین می‌کند. این پژوهش با ارائه راهکاری نوآورانه، شکاف علمی در زمینه کاهش نشت گاز ناشی از ذرات معلق را پر کرده و گامی مؤثر در جهت بهینه‌سازی مصرف انرژی برداشته است.

چکیده English

Natural gas, as a national asset and a vital energy source, requires preservation and prevention of waste. One of the main points of gas leakage is the low-pressure section of city gas regulators, where the accumulation of suspended particles in the diaphragm and malfunctioning lead to energy waste and economic damage. This study, in collaboration with the Gas Company of Mazandaran province, aims to reduce gas leakage through numerical simulation, design, and construction of optimized regulator prototypes. In this research, the effect of using flow-directing obstacles on reducing particle accumulation and improving flow distribution in the low-pressure section has been examined. Simulation results showed that the curved barrier model with an inlet-facing curvature could optimize the fluid flow path and reduce gas leakage by up to 25%. Furthermore, experimental results demonstrated that this model effectively prevents particle accumulation in the diaphragm seat and ensures stable regulator performance. By providing an innovative solution, this research fills a scientific gap in reducing gas leakage caused by suspended particles and makes a significant contribution to energy consumption optimization.
