Numerical Analysis of Erosion/Corrosion due to Gas Flow in Pipelines and Gas Stations

In this paper، the numerical analysis of erosion/corrosion in gas pipelines and gas stations were investigated using computational fluid dynamics. The effects of various parameters such as velocity، temperature، turbulence، tiny particles floating in gas، and multi-phases were analyzed. For this purpose، comprehensive information on gas stations was first collected. Then، equipment of gas stations and pipelines was modeled and created using Catia and Solidwork commercial software packages. Finally، the numerical results were obtained using the method of computational fluid dynamics by employing Gambit 2. 2. 30 and Fluent 6. 0 commercial tools. Several items of equipment such as pipe، valve، reducer، bend، etc. were considered in this analysis. The results proved that erosion/corrosion was increased by increasing velocity، temperature، turbulence، tiny particles floating in a gas، and multi-phases.
