The flow channel design on bipolar plates affects proton exchange membrane (PEM) fuel cell performance by influencing reactant distribution and water removal in an operating fuel cell. The fuel cell performance can be improved by varying the type, size, or arrangement of channels. Two ... 詳細を見る
Electrochemically-active conducting polymers (ECP) swell or shrink in response to ion and solvent incorporation or ejection as a result of electrochemical reaction of the polymer. When anodic potential is applied to an electrode attached to one end of ECP strip, the oxidation process ... 詳細を見る
When a solid surface makes contact with a liquid medium, an electrical double layer (EDL) structure forms spontaneously through thermodynamic interaction between electrons and ions. In this study, we developed a computational model using commercial finite element analysis package COMSOL ... 詳細を見る
Reactive extraction of organic acids from an aqueous solution to an alkaline stripping fluid is based on a selective barrier allowing permeation of non-polar molecules, which subsequently react with the stripping agent. The shift from the organic acid to its base induced by the chemical ... 詳細を見る
This work investigates the effects of boundary conditions on the species profiles in heterogeneous catalysis, with low Péclet systems. Hydrogen combustion in Helium was chosen because of the high diffusivities. Furthermore, already at T=300°C over a Pt catalyst, kinetics is ... 詳細を見る
Mathematical optimization can be used as a computational engine to generate the best solution for a given problem in a systematic and efficient way. In the context of monolithic converter systems, the parameter estimation problem (or inverse problem) is solved using Partial Differential ... 詳細を見る
As an effective method to cope with green-house gas emission, and to enhance oil recovery, injection of carbon dioxide into oil reservoirs has obtained increasing attentions. The flooding process involves complex phase behavior among oil, brine and CO2, and geochemical reaction between ... 詳細を見る
Low temperature fuel cells require hydrogen of high purity for electricity production to avoid catalyst poisoning. To purify hydrogenrich flue gases from hydrocarbon steam reforming membrane shift reactors with a metal membranes may be utilized. A model of a tubular membrane shift ... 詳細を見る
This paper addresses the modeling of a complex glass forming process as an example of a complex, nonlinear distributed parameter system. The system is modeled by a fluid dynamics approach, which means that the forming is regarded as a fluid with free surfaces. Here, the coupling of the ... 詳細を見る
The Molten Salt Reactor (MSR), proposed along with other five innovative concepts of fission nuclear reactor by the Generation IV International Forum (GIF-IV), represents a challenging task from the modeling perspective because of the strong coupling between neutronics and thermo ... 詳細を見る
