Gas-liquid falling film microreactors carry out fast exothermic and mass transfer limited reactions. Since the major rate limiting steps occur on the liquid side, it is important to account for a realistic liquid film profile within the reactor simulation. Based on realistic channel ...

The DOE BETO consortium "ChemCatBio" has developed a packed bed catalyst for use in a Catalytic Fast Pyrolysis (CFP) process for producing biofuels and chemicals from lignocellulosic biomass. Another BETO consortium known as "CCPC" (Consortium for Computational Physics and Chemistry) is ... En savoir plus
Steam drums of a nuclear power plant separate steam from the steam water mixture and sub cooled incoming feed water returns to the reactor. The entire feed water flow is delivered to the steam drum through the feed water sparger. The feed water sparger is provided with number of ... En savoir plus
This paper intends to show a model of a monolithic reactor for the autothermal reforming process (ATR), a process that uses hydrocarbons to produce H2. The ATR chemical reactions take place on the surface of monolith channels coated with a catalyst. The isothermal ATR reactor is modeled ... En savoir plus
Electrochemistry is inherent a surface process, requiring the transport of reagents towards the electrode surface. In electrochemical reactors this typically results in mass transfer limitation problems, limiting the yield and efficiency of the reactor. While the academic community is ... En savoir plus
Magnesium hydride (MgH2) has been one of the most promising hydrogen storage methods that can be applied to commercial hydrogen energy systems due to magnesium’s safety, low cost, and excellent storage capacity for hydrogen, compared to other reversible metal hydrides. But hydrogen ... En savoir plus
At Oak Ridge National Laboratory (ORNL), the COMSOL Multiphysics software has become a reliable and important resource to estimate and assess thermal safety margins for several nuclear applications. This poster presentation will highlight some of the ongoing activities in the following ... En savoir plus
Design of the Pressurized Water Reactors (PWRs) involves extensive calculations to verify the reactor safety criteria such as power peaking factor during the reactor lifetime. Coupling of neutronic calculations, thermal hydraulic calculations and other reactor phenomena requires a ... En savoir plus
A power supply is generally used in many electrical devices. In order to deliver uniform power irrespective of time variation, most plasma equipment also uses a power source. Therefore, the power condition in plasma simulations is essential. In time-dependent models using a current ... En savoir plus
Electrochemical reduction of CO2 to value added chemicals is a promising strategy to mitigate its emission from atmosphere and close the carbon cycle. Although the knowledge on designing electrocatalysts for CO2 electroreduction exists, challenges are associated with developing CO2 ... En savoir plus
