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.

Reactor Design Improvements for a Propane Autothermal Reformer by Simulation of Momentum Flow

CNR-ITAE, Messina

The paper presents a two-dimensional model to describe the gas flow in a propane autothermal reactor, developed at the CNR-ITAE Institute, and aimed to design a Beta 5 kWe hydrogen generator, named HYGen II, to be used with Polymer Electrolyte Fuel Cells (PEFCs) for residential applications. The main aim of the mathematical model was to optimize the reactor geometrical key parameters (diameter ...

Thermal Dissipation of DIMM Modules in a Tower-BTX Configuration

G. Sorge, G. Cammarata, and G. Petrone
University of Catania

In this paper we study the natural convection for Dual In-Line Memory Module (DIMM) systems. Numerical models are developed using COMSOL Multiphysics. The results, obtained for imposed ambient temperature and operative conditions (power supplied to the CPUs) were produced and complex fluid motion field could be detected.

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

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.
