The pore-scale behaviour of gas and water in rough-walled hydrophilic fractures is critical to understanding the gas production features of naturally fractured formations. In this study, the volume of fluid (VOF) approach is utilised to perform a systematic examination of gas and water flow characteristics in both single-fracture and Y-shaped junction fracture models. According to numerical simulations, the gas/water rate ratio altered the shape, phase distribution, and saturation of gas bubbles and slugs. The gas/water ratio has a bigger influence than fracture roughness and tortuosity, whereas total fluid rate has no effect. Because the channel aperture ratio alone controls the phase distribution and referential paths in Y-shaped junction models, the impact of the intersecting angle and fluid flow rate can be ignored.
