On the application of simplified rheological models of fluid in the hydraulic fracture problems
Michal Wrobel
In this paper we analyse a problem of a hydraulic fracture driven by a non-Newtonian shear-thinning fluid. For the PKN fracture geometry we consider three different rheological mod…

On the influence of fluid rheology on hydraulic fracture
Michal Wrobel, Gennady Mishuris, Panos Papanastasiou
We analyse a problem of a hydraulic fracture driven by a non-Newtonian shear-thinning fluid. Fluid viscosity is described by the four-parameter truncated power-law model. By varyin…

An efficient algorithm of solution for the flow of generalized Newtonian fluid in channels of simple geometries
Michal Wrobel
In this paper a problem of stationary flow of generalized Newtonian fluid in a thin channel is considered. An efficient algorithm of solution is proposed that includes a flexible p…
