Introduction
Gas pressure reduction stations play a critical role in ensuring the reliable and efficient transmission of natural gas. A key challenge in these stations is maintaining adequate gas temperature to prevent hydrate formation and flow obstructions, particularly during pressure reduction. Heaters are essential components in these stations to address this issue.
Accurate modeling and optimization of these heaters can significantly enhance the efficiency and safety of gas transmission systems. Computational Fluid Dynamics (CFD) software, such as COMSOL Multiphysics, provides a powerful tool for simulating the complex thermal and fluid flow phenomena within these heaters. By analyzing the effects of various parameters, such as flow rate, temperature, and pressure, engineers can optimize the design and operation of these heaters.
This research focuses on utilizing COMSOL to simulate gas pressure reduction station heaters. The primary objective is to accurately model the thermal and hydrodynamic processes within the heater, analyze the impact of temperature and pressure variations on system performance, and identify key parameters for optimization.
