Highly parallelisable simulations of time-dependent viscoplastic fluid flow with structured Numerical simulations of immiscible generalised Newtonian fluids.

An Eulerian thermomechanical elastic-viscoplastic model with Heat Transfer Prediction of In-Service Welding in a Forced Flow of Fluid.

19. 2.7 Bingham Viscoplastic Fluids . 21 Dec 2012 Based on the analysis of laminar flow of viscoplastic fluid in pipeline, an implicit equation to reveal the relationship between the effective shear shear-thickening, visco-plastic, time-dependent and visco-elastic behaviour are pre- sented. Each type of non-Newtonian fluid behaviour has been illustrated via 5 Dec 2017 Derivation of Kolmogorov microscales for viscoplastic fluids. • The role of of a large family of turbulent purely-viscous and viscoplastic fluid.

The Herschel-Bulkley law is used to model the fluid behavior. We present an assessment of viscosity regularization (VR) in predicting transient flows of viscoplastic fluids (VPF). Although VR has been the most popular In this work, a numerical simulation of a viscoplastic fluid flows through an axysimetric expansion followed by a contraction is performed.

The key feature of a viscoplastic fluid is its yield stress: material only flows like a fluid if the stresses exceed a critical yield threshold. The consequence for a cylinder moving through a viscoplastic fluid is that there is no motion if the force on the object is insufficient to yield the fluid. G. Ovarlez, S. Cohen-Addad, K. Krishan, J.

Withdrawal of water-capped viscoplastic fluid was investigated using laboratory experimentation and numerical modeling. The viscoplastic fluid was modeled using a Laponite suspension, which was withdrawn by a vertical pipe intake. Variations of the Laponite–water interface and intake configurations were investigated in this study.
