TLDR
The design of wire-coating dies is described using finite element numerical analysis as a guide and two basic die geometries are examined and a new design which eliminates recirculation within the die is proposed.Abstract:
The design of wire-coating dies is described using finite element numerical analysis as a guide. Finite elements are able to accommodate awkward geometries and non-Newtonian fluid properties in a realistic manner, and produce streamline and stress patterns within the die. Two basic die geometries are examined and a new design which eliminates recirculation within the die is proposed.read more

Flows of viscoplastic materials: models and computations
TL;DR: In this paper, a continuation parameter is introduced into the models to facilitate the solution process and produces virtually the same results as the ideal models by the right choice of its value, which can be used to track down yielded/unyielded regions.

Flows of viscoplastic materials: Models and computations
TL;DR: In this article, the Galerkin/finite element method and global Newton iteration are used to estimate the velocity and pressure fields of viscoplastic flows with yield surfaces, and the finite element scheme locates the characteristic material lines, such as interfaces and yield surfaces.

Steady MHD flow and heat transfer of a third grade fluid in wire coating analysis with temperature dependent viscosity
M. K. Nayak,G.C. Dash,L.P. Singh +2 more
TL;DR: In this paper, the effect of a radial magnetic field and varying temperature dependent viscosity on wire coating is analyzed in the presence of magnetic field in the extrusion die of a pressure type die and the equations characterizing the flow and heat transfer phenomena are solved numerically.

Numerical Flow Simulation of Viscoplastic Slurries and Design Criteria for a Tape Casting Unit
TL;DR: In this paper, a viscoplastic Bing-ham fluid with a yield stress was modeled as an organic-bonded alumina slurry and a new reservoir design with tapered walls avoiding recirculation was proposed.

The solution of viscous incompressible jet and free-surface flows using finite-element methods
TL;DR: In this paper, a finite element program suitable for solving incompressible, viscous free surface problems in steady axisymmetric or plane flows is presented. But the authors do not consider the non-Newtonian flow, non-zero Reynolds numbers, and transient flow.
