Morphological Modelling of a Metal Foam Supported SOFC Configuration

Numerical simulation of deformation of a metal foam Numerical simulation of deformation of a metal foam

Mathematical model for the description of deformation of a porous metal is constructed on the basis of generalized rheological method. In this method a new rheological element, so-called rigid contact, is used to describe the uniaxial deformation of materials with different resistance to tension and compression. Change in the resistance of a porous metal to external loads, when the collapse of ...

Modelling a SOFC Power Unit Using Natural Gas Fed Directly

GPU-supported bubble and foam rendering

Several types of foam can be found both in nature and artificial environments; yet it is rare in computer graphics due to its complexity. Modelling foam structure and dynamics by simulating the underlying bubble structure has a high computational cost. To model such a complex phenomena we need to use serious simplifications while maintaining realism and detail. In this paper we propose a method...

Modeling and Control of a Sofc-gt Hybrid System with Single Shaft Configuration

This article focuses on issues related to control and operability of a Solid Oxide Fuel Cell (SOFC) Gas Turbine (GT) hybrid system with single-shaft GT configuration. The models of all the components of the hybrid system are developed and integrated to constitute the hybrid system. An autonomous power grid is modeled as load. The main control objectives considered are control of Fuel Utilizatio...

Metal Foam and Finned Metal Foam Heat Sinks for Electronics Cooling in Buoyancy-Induced Convection

In this paper, we present our recent experimental results on buoyancy-induced convection in aluminum metal foams of different pore densities [corresponding to 5, 10, 20, and 40 pores per in. (PPI)] and porosities (0.89–0.96). The results show that compared to a heated surface, the heat transfer coefficients in these heat sinks are five to six times higher. However, when compared to commercially...
