Gas distribution inside an MCFC

An analysis for a molten carbonate fuel cell of complex geometry using three-dimensional transport equations with electrochemical reactions

“…(1) can be determined from the pressure drops for a few Reynolds number flows and boundary condition is showed in Table 3. Marra et al [20,21] calculated 3D periodic module of current collector which adopted in our study similarly. Marra et al [20,21] set no-slip condition in top and bottom wall, however we applied symmetric condition top and bottom wall in our research.…”

Marra et al [20,21] set no-slip condition in top and bottom wall, however we applied symmetric condition top and bottom wall in our research. If a periodic module has no-slip condition in top and bottom wall, MCFC unit cell has also wall effect in top and bottom.…”

A multi-physical simulation on the IAQ in a movie theatre equipped by different ventilating systems

“…Specific applications of the adopted numerical tool in solving thermal and fluid-dynamical problems, both directly concerning building simulation (Lin and Zmeureanu 2008;van Schijndel 2009;Zhang and Wachenfeldt 2009) and other fields of interest (Cardiff and Kitanidis 2008;Comini and Savino 2009;Henriques et al 2010;Fries and von Rohr 2009;Kosar 2010;Lorenzini and Casalena 2008;Marra 2008;Shi and Wang 2008;Sun et al 2006;Wissmeier and Barry 2011;Wu et al 2010;Xu et al 2009) can be found in the up-to-date literature. A validation study concerning the accuracy of COMSOL Multiphysics in solving standard computational fluid dynamics (CFD) benchmarks has been recently performed by Pepper and Wang (2009), that showed a good agreement of COMSOL Multiphysics results with experimental data and results obtained by other CFD commercial software.…”

Entropy Generation Minimization for the Optimal Design of the Fluid Distribution System in a Circular MCFC

“…Detailed models have been used to understand fuel and oxidant distribution in multi-channels cells (Ma et al, 2003), effects of internal reforming (Park et al, 2002), and ions dynamics (Bittanti et al, 2006). Fluid-dynamic analysis has also been performed in order to study current collectors (Marra, 2008) and simulate electrochemical kinetics (Fontes et al, 1995). Plant energetic and system optimization incorporating MCFC power units has been also tackled, in particular cogeneration (Cigolotti et al, 2008) and electricity-hydrogen production systems (Verda and Nicolin, 2010).…”
