Abstract

In this article, extensional rheological data of various polymer solutions, to be used in Azad Trivedi viscoelastic model (AT-VEM) for predicting the viscoelastic behavior of synthetic polymer in porous media are provided. Extensional rheology measurements are performed for different polymer solutions using Capillary breakup extensional Rheometer (CaBER) to obtain the filament diameter with respect to time. Extensional rheological parameters, such as the extensional relaxation time, maximum elongational viscosity at the critical Deborah number and strain hardening index are determined from observed filament diameter with time-based on the Upper Convected Maxwell model, the finite extensible non-linear elastic model, and the power law model.

摘要

本文提供了各种聚合物溶液的拉伸流变数据，这些数据将用于阿扎德·特里维迪粘弹性模型（AT-VEM），以预测合成聚合物在多孔介质中的粘弹性行为。使用毛细管破裂拉伸流变仪（CaBER）对不同的聚合物溶液进行拉伸流变测量，以获得细丝直径随时间的变化。基于上随体麦克斯韦模型、有限可拉伸非线性弹性模型和幂律模型，根据观察到的细丝直径随时间的变化，确定拉伸流变参数，如拉伸松弛时间、临界德博拉数下的最大拉伸粘度和应变硬化指数。
