"VCM Model Predictions in Steady and Transient Shearing Flows"


The two species, scission/reforming Vasquez-Cook-McKinley (VCM) model was formulated to describe the coupling between the viscoelastic fluid rheology and the kinetics of wormlike micellar assembly and deformation-induced rupture. In this talk I will present a comprehensive investigation of the full VCM model in steady and transient shearing flow including inertial and diffusive (non-local) effects.The consequences of varying the model parameters, the effect of the start-upramp rate, and the role of geometry (Taylor-Couette versus channel flow) on the steady state flow curve are each investigated. The complete time evolution of the rheological response is examined, from the initial formation of inertial waves (and consequent potential transient multiple banded states), shear band formation (and elastic recoil in the local velocity), to the long time diffusion-mediated approach to a final steady state.
