Simulation of the Inverse Extrusion of a Brass Rod by the Coupling of Fluid, Mechanical, Thermal and Ale Modules

C. Mapelli, and L. Bergami
Politecnico di Milano

An efficient simulation of the inverse extrusion process has been performed through the coupling of three modules in COMSOL Multiphysics: fluid-dynamics, general heat transfer and ALE. The strain, the strain rate, and the stress field can be completely defined after the complete definition of the velocity field of the material under the action of the tool. The definition of the stresses and of ...

Heat and mass transfer can be analyzed for conditions that may limit shelf-life. With this target, the purpose of the present work is the development of a general model which is applicable to a large variety of packaging configurations, food products and environmental conditions. To this end, COMSOL Multiphysics is exploited in a full 3D geometry.

A Model for Tubular Solid Oxide Fuel Cells

C. Ciano
Politecnico di Torino

In this paper, a model of a tubular fuel cell is proposed and includes thermo-fluid dynamics, chemical reactions and electrochemistry. The main results presented are the temperature distribution, the concentration of species and the polarization curves.

Simulation of the Inverse Extrusion of Brass Rod by the Coupling of Fluid Mechanical, Thermal and ALE Modes

C. Mapelli, and L. Bergami
Dipartimento di Meccanica, Politecnico di Milano

The complete coupling among the Incompressible Navier-Stokes - General Heat Transfer -ALE modes can be a reliable tool for the simulation of the plastic deformation process. This is shown here.
