| المستخلص: | The amphiphilic polymers have a lot of particular physical and chemical properties such as; the aggregation shape and size, the hydrophilic and the lipophilic segments, etc. The researchers on amphiphilic polymers focus on polymers material field. The important theories and signification in using amphiphilic polymers are known to all with its good performances in many fields. In this work initially, the Giesekus model was used to study the rheology of the amphiphilic polymers solution. The Giesekus model includes three parameters that describe any used polymer, and the parameters were selected from the literature data. A mathlab code was created to simulate the Giesekus model. The obtained results showed shear thinning at the shear rate range. Finally, the Hydrophilic-Lipophilic Deviation (HLD) and Net-Average Curvature (NAC) model was presented. The HLD_NAC model was used to predict the phase behavior of microemulsion and the properties of microemulsion. Depending on microemulsion morphology, some models from literature were presented to predict the microemulsion rheology. The predicted microemulsion morphology and viscosity may be useful in the design of formulations for enhanced oil recovery. |
