DOI: 10.1103/physrevapplied.8.064029
Abstract: Multiphase flows in deformable porous materials are important in numerous geological and geotechnical applications, however the complex flow behaviour make subsurface transport processes difficult to control or even characterise. Here we study gas-driven (pneumatic) fracturing… read more here.
