The modeling of Bingham materials is of crucial importance in industrial applications, since a large variety of materials (e.g. foams, pastes, slurries, oils, ceramics, etc.) exhibit the fundamental character of viscoplasticity, that is the capability of flowing only if the stress is above some critical value. 4th Workshop on Viscoplastic Fluids: From Theory to Application – Rio de Janeiro, Brazil, November 6-10, 2011 FOREWORD These proceedings contain the abstracts of the presentations of the Fourth Workshop "Viscoplastic Fluid: From Theory to Application," held at Marina Palace Hotel in Rio de Janeiro, RJ, Brazil, on November 6-10, 2011. 2019-11-23 This special issue contains papers based on work presented at the workshop: Viscoplastic Fluids, from Theory to Application, held in Cambridge UK, September 2019.

Abstract. Bingham fluids constitute a very important class of non-Newtonian fluids. The modeling of Bingham materials is of crucial importance in industrial applications, since a large variety of materials (e.g. foams, pastes, slurries, oils, ceramics, etc.) exhibit the fundamental character of viscoplasticity, that is the capability of flowing only if the stress is above some critical value. 4th Workshop on Viscoplastic Fluids: From Theory to Application – Rio de Janeiro, Brazil, November 6-10, 2011 FOREWORD These proceedings contain the abstracts of the presentations of the Fourth Workshop "Viscoplastic Fluid: From Theory to Application," held at Marina Palace Hotel in Rio de Janeiro, RJ, Brazil, on November 6-10, 2011. 2019-11-23 This special issue contains papers based on work presented at the workshop: Viscoplastic Fluids, from Theory to Application, held in Cambridge UK, September 2019.

Example models of viscoplastic liquids include Bingham plastic, Hershel-Bulkley and Casson (there is a detailed discussion in the link). For Viscoelastic models, the simplest are the Maxwell and

Regarding the viscoplastic fluid flow past triple cylinders (as mentioned in the Introduction), to the best of the authors’ knowledge, this is the first study that examines the interaction between the cylinders and the unyielded regions around the objects in the presence of the viscoplastic fluid.

4th Workshop on Viscoplastic Fluids: From Theory to Application – Rio de Janeiro, Brazil, November 6-10, 2011 FOREWORD These proceedings contain the abstracts of the presentations of the Fourth Workshop "Viscoplastic Fluid: From Theory to Application," held at Marina Palace Hotel in Rio de Janeiro, RJ, Brazil, on November 6-10, 2011. The rheological behavior of the viscoplastic fluids is represented by the Herschel‐Bulkley viscosity function. The deformation behavior of commonly encountered viscoplastic fluids is generally complicated by the presence of wall slip at solid walls, which is a function of the wall shear stress. Viscoplastic fluids rheology exhibit the so-called 'yield stress, τ 0 ' that governs the transition from solid-like to liquid-like response 1.

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. One of the goals is to drilling fluid is typically a viscoplastic fluid of pseudoplastic nature whose viscosity of viscoplastic fluids in concentric, eccentric, as well as irreg- ular eccentric A constitutive model for structured fluids is presented. Its predictive capability includes thixotropy, viscoelasticity and yielding behavior. It is composed by two The viscoplastic fluid has been simulated by the exact Bingham model without any regulations. Lattice Boltzmann Method (LBM) has been applied to solve the Abstract This work is concerned with computational modelling of viscoplastic fluids. The flows considered are assumed to be incompressible, while the These notes are intended to supplement a short lecture course covering the theoretical background of the dynamics of ideal visco-plastic fluids, e.g.

Viscoplastic materials behave as solids subject to a small applied force, but flow like a fluid when the applied force is large enough. Such materials are very common: in the home, mustard, hair gel, and face cream are all viscoplastic fluids. Some traditional viscoplastic materials in some non-traditional flow configurations, and some non-traditional viscoplastic fluid flows (plus pertinent references), from top right to bottom left Following Fusi et al.
