Dynamics of fluid-driven fractures in the viscous-dominated regime
Sri Savya Tanikella, Marie C Sigallon, Emilie Dressaire
During hydraulic fracturing, the injection of a pressurized fluid in a brittle elastic medium leads to the formation and growth of fluid-filled fractures. A disc-like or penny-shap…

Axisymmetric displacement flows in fluid-driven fractures
Sri Savya Tanikella, Emilie Dressaire
Displacement flows are common in hydraulic fracturing, as fracking fluids of different composition are injected sequentially in the fracture. The injection of an immiscible fluid a…

Dynamics of fluid-driven fractures across material heterogeneities
Sri Savya Tanikella, Marie C Sigallon, Emilie Dressaire
Fracture propagation is highly sensitive to the conditions at the crack tip. In heterogeneous materials, microscale obstacles can cause propagation instabilities. Macroscopic heter…
