Multiphase, Dual Polymer Injection Molding and Cooling of an Open Cavity to Form both Distinct and Graduated Material Properties within a Complex Three-Dimensional Body
With the advancement of medical devices and implants, many now require more advanced nonlinear, hyper-elastic materials such as elastomers to be extensively utilized in the body. This combined with the need to allow for considerably different, varying and graduated material responses ... Read More
Acid-Base Reactions Enhancing Membrane Separation: Model Development and Implementation
Reactive extraction of organic acids from an aqueous solution to an alkaline stripping fluid is based on a selective barrier allowing permeation of non-polar molecules, which subsequently react with the stripping agent. The shift from the organic acid to its base induced by the chemical ... Read More

Including Expert Knowledge in Finite Element Models by Means of Fuzzy Based Parameter Estimation
In this paper we present a novel approach for modeling spatial distributed bio- chemical and environmental processes like the growth of plants and the related biochemical reactions. The physical phenomena like flow and mass transport can be described by fluid dynamics equations, but for ... Read More
COMSOL Multiphysics® as a Tool to Increase Safety in the Handling of Acetylene Cylinders Involved in Fires
In this paper a mathematical model for predicting the heating-up of an acetylene cylinder involved in a fire is presented. In the simulations polynomial functions were used to describe the temperature dependency of the thermal properties of the cylinder interior, which is a complex ... Read More
Providing an Entry Length in Heterogeneous Catalytic Reactors with Fast Diffusion
This work investigates the effects of boundary conditions on the species profiles in heterogeneous catalysis, with low Péclet systems. Hydrogen combustion in Helium was chosen because of the high diffusivities. Furthermore, already at T=300°C over a Pt catalyst, kinetics is ... Read More
Second Order Drift Forces on "Offshore" Wave Energy Converters
Objective of this contribution is to present a procedure for evaluating second order drift forces on floating bodies, often the most important loading component for mooring design, in case of high waves propagating in relatively shallow water depths. The non linearity associated to this ... Read More
Numerical Simulation of Granular Solids’ Behaviour: Interaction with Gas
In previous works a dissipative hydrodynamic model was used to simulate the behavior of a dense granular solid flowing through silos with simple geometries or with internal devices, showing good agreement with experimental results. That model has been upgraded taking into account the ... Read More
Effects of the Film Thickness on the Transient Conjugate Opticalthermal Fields in Thin Films Irradiated by Moving Sources in Back and Front Treatments
A two dimensional transient analysis of the conjugate optical-thermal fields induced in a multilayer thin film structure by a moving Gaussian laser source is carried out numerically in order to compare back and front laser treatment processes. Thermal and optical nonlinearity is induced ... Read More
