Computational fluid dynamics numerical methodology

This chapter provides an introduction to SOFC technology for stationary power generation. A 2D numerical model is developed by coupling the computational fluid dynamics (CFD) methodology with the electrochemical and chemical reaction kinetics. The rates of chemical reaction and electrochemical reaction as well as corresponding reaction heats are implemented in the CFD model as source terms. 

A single set of conservation eqnations valid for both porous electrodes and the free electrolyte region is derived and nnmerically solved using a computational fluid dynamics technique. This numerical methodology is capable of simulating a two-dimensional cell with the fluid flow taken into consideration. The motion of the liquid electrolyte is governed by the Navier-Stokes equation with the Boussinesq approximation and the continuity equation as follows ... 

Mass transfer processes are complicated, usually involving turbulent flow, heat transfer, multiple phases, chemical reactions, unsteady operation, as well as the influences from internal construction of the equipment and many other factors. To study such complicated system, we propose a novel scientific computing framework in which all the relevant equations on mass transfer, fluid-dynamics, heat transfer, chemical reactions, and all other influencing factors are involved and solved numerically. This is the main task and research methodology of computational mass transfer (CMT).
