Coupled CFD–DEM analysis of soil cavity formation and gas diffusion during buried pipeline leakage

Abstract After the leakage of a buried pipeline, the overlying soil structure deforms under the high-speed impact of escaping gas, influencing both leakage and diffusion behaviours. This deformation typically appears as a soil cavity above the leakage port, especially in medium- and low-pressure conditions. In this stu...
