Abstract
The material functions of multiple EOR polymers were measured and analyzed. Investigating the start-up and relaxation behaviour of multiple polymeric solutions were the main focus of this thesis work. The experimented data were analyzed and compared with Charged-FENE-P Dumbbell model qualitatively. And it has been discovered that Finitely Extensible Nonlinear Elastic-Peterlin (FENE-P) cannot predict the sudden decay of shear stress at sudden relaxation while Charged-FENE-P is able to predict and explain the behavior. The shear thinning viscosity of polymer was analyzed against FENE-P dumbbell model and exponential Phan-Thien-Tanner model (PTT) for different concentrations. The storage and loss moduli data were compared with C-FENE-P Dumbbell model. It has been concluded that both shear stress growth rate at the beginning of a shear flow and shear stress decay rate after sudden cessation of the flow not only depends on the concentration and shear rate but also on the molecular weight of the polymer. This outcome can be implemented to reduce the shear thinning behavior of the polymer at a sudden stage. But further investigations are needed. With further investigation, this outcome can be implemented in both technical and experimental fields.
