Description
In this work, we have studied numerically the fracture initiation conditions induced by non-Newtonian polymer solution in the granular media. Computational Fluid Dynamics (CFD) coupled with the Discrete Element Method (DEM) technique is used to model fluid flow through porous media. The power law used to describe the polymer solution flow. The associated parameters are considered in the drag force computation for CFD-DEM framework. The numerical model is validated by the laboratory experimental data [1]. The results of the different polymer solutions are presented in the proposed criteria of fracture initiation. The impact of fluid rheology, injection rate, stress conditions, and granular material parameters on the fracture model is presented.
