This paper reports on the numerical simulation of rotating flows with free surfaces, typically that arise in dough-kneading situations found within the food processing industry. Free-surface flow in a rotating cylinder is investigated when a fluid is

This work describes the implementation of an adaptive procedure for viscoelastic flows. Finite element simulations are conducted using a Taylor-Galerkin/pressure correction scheme. The constitutive equations considered are those for an Oldroyd-B and

This paper investigates the convergence properties of iterative schemes for the solution of finite element mass matrix equations that arise through the application of a Taylor-Galerkin algorithm to solve instationary Navier-Stokes equations. This is

A number of different model transient flow problems are solved using a finite element algorithm. This algorithm is benchmarked against analytical solutions for both pure diffusion and convection-diffusion problems in two dimensions, and the relative

In a variety of industrial applications, modelling compressible inelastic free-surface flows remains a numerical challenge. This is largely due to the physical phenomena involved and the computational cost associated with the simulations of such flow

In this paper we consider methods of gradient recovery in the context of primitive-variable finite-element solutions of viscous flow problems. Two methods are considered: a global method based on a Galerkin weighted residual procedure, and a direct m

In this paper, we explore the ability of network‐type models (Phan‐Thien/Tanner PTT) to reflect enhanced pressure drops in contraction/expansion flows (ratio 4:1:4). Severe strain hardening is captured through suitable parametric control, whilst

This study investigates the application of a new hybrid finite element/finite volume scheme to the numerical solution of some viscoelastic flows. Such an FE/FV approach (see similarly Sato and Richardson [3]) is contrasted against a purely finite ele

Various aspects of numerical simulation for filling problems related to injection moulding are addressed. Two front tracking techniques are studied, one based on particle tracking and the other on source propagation. Both isothermal and non-isotherma

Over the past two years or so, work has been under way at Swansea to develop a computer code for simulating transient flows of non-Newtonian materials. The code is based on an algorithm presented in Townsend and Webster [1] and makes use of a Taylor-
