Constructing COMSOL Models of a Bacteriological Fuel Cell
We have started constructing preliminary design COMSOL models of a bacteriologically driven \'fuel cell\' that is intended to process waste products, such as carbon dioxide and brine, from a crewed vehicle. At this early stage, this complex system is reduced to two electrodes separated ... Mehr lesen
Modeling the Chemical Decomposition of Sodium Carbonate Peroxyhydrate
The challenge with the use of Sodium Carbonate Peroxyhydrate (Na2CO3*1.5H2O2) as a bleach source in dry detergent formulations is its lower stability in comparison with other materials, and the risk of quality losses of the product over the shelf life. The issue can be solved with the ... Mehr lesen
Humidity Mass Transfer Analysis in Packed Powder Detergents
Powder detergents containing sodium percarbonate and bleach activators undergo chemical decomposition when exposed to high relative humidity. Controlling the moisture intake in finished product packs is therefore a fundamental need in order to guarantee product stability during the whole ... Mehr lesen
Numerical Modeling of Pit Growth in Microstructure
Pitting corrosion is a complex phenomenon where rates of: i) chemical reactions, ii) diffusion of various species involve in those reactions, and iii) species dissolution at the metal-electrolyte interface are fully dependent on each other, except under special conditions or assumptions. ...

Modeling of Transport and Reaction in a Catalytic Bed Using a Catalyst Particle Model
A packed bed reactor consisting of spherical catalyst particles in a tube was simulated numerically. The steady-state pseudo-heterogeneous model consisted of a pseudo-continuum representation for the heat and mass transfer in the reactor tube. The reaction source terms were evaluated by ...

Simulation of a Magnetophoretic Device for the Separation of Colloidal Particles in Magnetic Fluids
Magnetophoresis of non-magnetic particles is the induced motion of non-magnetic particles suspended in magnetic media on the application of a magnetic field gradient. Magnetophoresis can be used in special separation devices to separate colloidal particles based on their sizes. ... Mehr lesen
Simulation of Methane Adsorption in ANG Storage System
Recently adsorptive storage has been identified as the most promising low-pressure (3.5 - 4.0 MPa) alternative for storing natural gas for vehicular use. However in order to successfully implement this technology, the filling and discharge characteristics of the adsorbent bed must be ... Mehr lesen
Model of Combustion Synthesis of Thermoelectric Calcium Cobaltates
Self-propagating High-temperature Synthesis (SHS), a very economical synthesis of oxides was used in our lab to produce oxide materials. SHS process uses a highly exothermic reaction to convert reactants rapidly to pure products with minimal external energy input. This reaction is ... Mehr lesen
Numerical Investigation of Mass Transfer with Two-Phase Slug Flow in a Capillary
The multiphase flow of two immiscible liquids in a microchannel was investigated numerically. A Y-shape micromixer was designed to produce a pattern of slugs from the flowing liquids. The mass transfer characteristics of this flow pattern are of primary interest in this study. A simple ... Mehr lesen
Design Simulations of a General Purpose Research Micro Reactor for Methane Conversion to Syngas.
A general purpose stainless steel micro reactor setup for methane conversion is being designed for research purposes. We intend to design and build a modular device that would be able to manage different types of reactions depending on the installed modules. The device should be able to ... Mehr lesen
