Distributed Parallel Computation with Multi-mode Viscoelastic models of Wire-Coating Flows
نویسندگان
چکیده
Wire-coating flow is simulated, involving polymer melt coatings and tube-tooling process design. A finite element method is employed, based on a semi-implicit time-stepping Taylor-Galerkin/pressure-correction scheme. The exponential Phan-Thien/Tanner model is used in its multi-mode form to represent a high-density polyethelyne (HDPE) polymer. Both shear-thinning and elongation-softening properties are represented. Solutions are generated through sequential and parallel modes of computation, over a homogeneous network cluster of Intel workstations running Solaris and Parallel Virtual Machine (PVM). Parallel results are compared against those obtained on a single processor (sequential). Linear speed-up is observed with the number of processors.

A time-stepping nite element method is used to predict the viscoelastic stresses that arise in a tube-tooling wire-coating problem. The polymer melt HDPE is modelled by a multi-mode Phan-Thien/Tanner constitutive equation. Di erent ow geometries are considered to address optimisation of the process with respect to minimising the stress induced within the coating produced. The in uence of the di...

The aim of a multi-mode resource-constrained project scheduling problem (MRCPSP) is to assign resource(s) with the restricted capacity to an execution mode of activities by considering relationship constraints, to achieve pre-determined objective(s). These goals vary with managers or decision makers of any organization who should determine suitable objective(s) considering organization strategi...

The numerical simulation of two-dimensional incompressible complex flows of viscoelastic fluids is presented. The context is one, relevant to the food industry, of mixing within a cylindrical vessel, where stirrers are located on the lid of the vessel. Here, the motion is considered as driven by the rotation of the outer vessel wall, with various stirrer locations. With a single stirrer, both a...
