We consider two types of non-Newtonian rheology: truncated power-law fluid and Bingham fluid.
For the two types of non-Newtonian rheology, we construct relations between the superficial fluid velocity and the pressure gradient in fractures and porous media.
The above formulations are implemented within the open-source MATLAB Reservoir Simulation Toolbox (MRST). Discrete fracture model (DFM) is employed to incorporate the flow in fractures and porous media.
We report simulations of flow in rough-walled fractures for different rheologies and study the effect of fluid parameters on the flow channelization in rough-walled fractures. This effect is known from experiments and from previous numerical studies.
