The Flow of Viscoelastic Polymer Solution in Porous Media

Hydrophobically associating polymers for enhanced oil recovery – Part B: A review of modelling approach to flow in porous media

“…The difficulty with modelling polymer rheology lies in the fact that they are non-Newtonian fluids and the porous media in which they flow is a non-uniform pore geometry (Lohne et al, 2017;Skauge et al, 2018). The analytical study of polymer flow in porous media involves the use of time-independent models with the addition of some viscoelastic attributes (Delshad et al, Journal Pre-proof J o u r n a l P r e -p r o o f 2008; Sochi, 2010;Hatzignatiou et al, 2013;Yang et al, 2015). This can be represented as shown in equation (2):(2) Where represents the shear-thinning component.…”

“…However, regardless of the approach employed (either equation 2 The model is simplistic in form and its application is limited due to lack of clarity in differentiating between the shear thinning and shear thickening stage (Yang et al, 2015). In other words, accurate prediction of the onset of shear thickening is not captured by the model.…”

“…or (3)), a general classification of viscosity models for polymer flow in porous media was grouped into two byYang et al (2015). This classification was based on the number of parameters contained in the model: two parameter and multi-parameter models.…”

Viscoelastic effects on the oscillatory flow in a fluid‐saturated porous layer

“…Marinca and Herişanu 41 studied the continuous two‐dimensional flow of a Walters‐type B' viscoelastic fluid in a vertical channel with a porous wall. Yang et al 42 discussed the solution of viscoelastic polymer flow through porous media. Venkateswarlu et al 43 studied the effects of chemical reactions and heat sources on the MHD oscillatory flow of a viscoelastic fluid in a vertical porous channel.…”
