Simulation of Gas Purge Process in City Gas Pipe
In this study, the simulation method of gas purge process in city gas pipe is proposed. In the concentration simulation, more detailed mesh was used. In addition, the CIP method was used to reduce the numeric diffusion. In experiment, the gas mixture that consists of air and carbon dioxide is used. The purge process of gas is measured by using a venturi flowmeter and a laminar flowmeter, and the simulation results were compared with experimental results. As a result, the simulation results have a good agreement with experimental results.
