Steady Herschel–Bulkley fluid flow in three-dimensional expansions
Abstract In this paper we study steady flow of Herschel–Bulkley fluids in a canonical three-dimensional expansion. The fluid behavior was modeled using a regularized continuous constitutive relation,Expand

On the determination of yield surfaces in Herschel-Bulkley fluids
Herschel–Bulkley fluids are materials that behave as rigid solids when the local stress τ is lower than a finite yield stress τ0, and flow as nonlinearly viscous fluids for τ>τ0. The flow domain thenExpand

Thixotropic rheology of semisolid metal suspensions
Abstract Understanding the time-dependent flow behavior of semisolid materials (SSM) is essential for the simulation of semisolid processes. During processing, the structure of the material changesExpand

Flow development of Herschel–Bulkley fluids in a sudden three-dimensional square expansion
The flow development of Herschel–Bulkley fluids in a sudden three-dimensional square expansion is studied numerically. The flow is modeled using the mixed-Galerkin finite element formulation to solveExpand

An inverse finite element method for directly formulated free boundary problems
In free boundary problems, in addition to the primary field variables, velocity, pressure and temperature, unknown geometric parameters need to be evaluated. A characteristic feature of the problemsExpand

Shear rejuvenation, aging and shear banding in yield stress fluids
The purpose of this work is to simulate shear rejuvenation and aging effects in shear thinning yield stress fluids in a typical rotational rheometer and to provide a common framework to describe theExpand
