Two-fluid model for nonlinear flow of wormlike micelle solutions. I: Model

November 1, 2024
Author(s)
Paul Salipante, Michael Cromer, Steven D. Hudson
We develop a rheological model to approximate the nonlinear rheology of wormlike micelles using two constitutive models to represent a structural transition at high shear rates. The model is intended to describe the behavior of semidilute wormlike micellar
