Stability of flows with the BMP model in the yield stress limit

Shear layers and plugs in the capillary flow of wormlike micellar gels

“…It can be looked at as a flow test that can provide insight into how elasticity, for instance, can really alter flow profiles and behaviour. 101 It would be interesting to search for analogues of such a test with similar materials in other flows, for example a Couette flow in the rheometer. 50 Our experiment reinforces WLM gels as an interesting complex material, distinct from other conventional WLM solutions.…”

“…Note, this stoppage flow is distinct from a flow in which forcing (Δ p ) is set to zero and resulting transient in decay in velocity can be then measured by solving the energy equation coupled to stress evolution. 101 Here, we set Q = 0. In principle, this should ensure that the velocity becomes instantly vanishes everywhere (owing to incompressibility of the fluid) to satisfy continuity.…”

“…Finally, replacing 2 9 γ by Dpuq and 9 τ by the upper-convected tensor derivative, we exactly obtain relations ( 1)-( 2) of the BMP model, as formulated in [5]. See also [39] for a different thermodynamic approach of the BMP model and [18] for an investigation of the yield stress limit ϕ 0 " 0.…”
