This study addresses the influence of pore size variation on effective thermal conductivity open-cell foam structures. Numerical design procedure which renders it possible to control chosen structural parameters has been developed based characterization commercially available copper foams. Open-porous materials with various distribution were numerically designed using Laguerre–Voronoi Tessellations procedure. Heat transfer through an isolated structure was simulated finite element method....
In the present paper, advanced characterization and modeling techniques are combined to analyze microstructure of open-porous tape-cast materials its influence on permeability. Four samples with different pore former content were fabricated via tape casting method. Subsequent firing manufactured green tapes allowed obtain structures porosity in range 45–50%. Quantitative image analysis 3D micro-computed tomography data was performed detailed porous characteristics obtained. Based acquired...
This paper demonstrates the benefits of using a metallic foam support within molten carbonate fuel cell (MCFC) cathodes. A state-of-the-art fabrication process based on tape casting has been developed to produce microporous electrodes with nickel scaffold. Surfactant was added control depth which slurry infiltrated foam. New cathodes were used as an alternative traditional cathode in single assembly and tested for power density. Mechanical properties compared current state-of-the-art. The...
This article deals with a thermal energy storage system in the form of water tank thermocline. The well-known thermocline phenomenon is modeled using computational fluid dynamics (CFD). However, reservoir model proposed this zero-dimensional. due to fact that aim build mathematical will be more useful models complex systems which hot one many elements system. In such zero-dimensional model, equations describing heat transfer, and itself treated as transfer surface known dimensions...
In the present paper two representative models applied for modeling of types porous materials - open-cell foams and open-porosity tapes are addressed. Algorithms presented here base on Laguerre-Voronoi tessellations (open-cell foams) sphere representation (open-porosity tapes) enable creating desired porosity pore size distribution. The geometrical features models, such as: porosity, mean size, cell diameter distribution number faces per were compared with those obtained by 3D micro-computed...
The paper presents the spectrum of methods and results for design structures, which are frequently applied in numerical simulations properties processes taking place cellular materials. described here universal many applications at various length-scales. They can be efficiently complex structures such as polycrystals or foams, where elements (grains pores) distributed shaped a controlled way. digital material representations created by these used number techniques as: Molecular dynamics...
Elastic properties of open-cell metallic foams are investigated in correlation with relative density and pore size variation. A variety foam architectures, open porosity above 70% (relative below 0.30) various distributions, were modeled using Laguerre-Voronoi tessellations (LVT). The coefficient volume variation, CV(V), was introduced to quantify the uniformity designed structures ranged between 0.5 2.1. behavior uniaxial compression along three orthogonal directions analyzed finite element...
