Simulations of Johnson-Segalman viscoelastic fluids flows in shear-thinning regime
Original language description
This paper presents selected numerical simulations performed using Johnson-Segalman model with specific setting of the convected derivative resulting in shear-thinning behavior of the model. The results are compared with the generalized Oldroyd-B model, which is typically used to simulate shear-thinning viscoelastic flows. Both models are solved using an in-house finite-volume solver on structured grid simulating steady flow in three-dimensional axisymmetric channel with smooth contraction. The results presented here focus on the flow recirculation behind the contraction and the structure of the forces emanating from the viscoelastic stress tensor.
