Electrical field effect on CO2 absorption and chemisorption in a rectangular bubble column by COMSOL nouveau
The chemisorption and absorption of CO2 bubbles have been extensively studied and modeled in literature. CO2 gas is converted into aqueous CO2, which produces OH-, HCO3- and CO32- - ions in the solution. In this study, a 3D CO2 bubble column is simulated using COMSOL Multiphysics, ... En savoir plus
Mechanical Stability and Flow Analysis of Hollow Microneedle array for Transdermal Drug Delivery nouveau
Transdermal drug delivery is an emerging mechanism for continuous systematic solutions in medical healthcare problem. Transdermal drug delivery has significant advantages when compared to conventional methods such as oral administration or intramuscular injection. Most of the ... En savoir plus
Non-uniform magnetic field-induced performance alteration of a topology-optimized PBMR nouveau
Packed bed microreactors (PBMR) and ferrofluids are independently enormously used in a broad range of applications in the healthcare sector. In a PBMR, one of the primary factors for controlling the reaction rate is the bed porosity which immediately affects the catalyst distribution and ... En savoir plus
Electromagnetic flowmeter coil design nouveau
Working on Faraday’s law of electromagnetic induction, electromagnetic flowmeters measure flowrate on the basis of the electric potential induced when a magnetic flux interacts with flowing water. The electromagnetic coils of the flowmeter are crucial to its operation, given that the ... En savoir plus
Multiphysics Modeling Results for the High Flux Isotope Reactor to Support its LEU Conversion
Ongoing engineering design studies at Oak Ridge National Laboratory are exploring the feasibility of converting the High Flux Isotope Reactor (HFIR) from highly enriched uranium (HEU) to low-enriched uranium (LEU) fuel. HFIR is a pressurized light water-cooled and moderated research ... En savoir plus
Modelling of Custom-Made Photocatalytic Wind Tunnel for Air Purification by Solar Photocatalysis
Heterogeneous photocatalysis an advanced oxidation process (AOP) which in combination with a catalyst and UV irradiation completely mineralizes organic pollutants from water or gases into harmless compounds such as carbon dioxide (CO2) and water (H2O). Photocatalysis as a process is ... En savoir plus
Elastohydrodynamics of Roll-to-Plate Nanoimprinting on Non-Flat Substrates
Roll-to-plate nanoimprinting is a manufacturing method to replicate micro- and nanotextures on large-area substrates with UV-curable resins. Figure 1 shows a schematic of the roll-to-plate imprint process, which is considered in this study [1]. It uses several rollers, for imprinting and ... En savoir plus
Modeling and Multiphysics Simulation of the Directed Energy Deposition Additive Manufacturing
In this paper, we present a study of the simulation of Directed Energy Deposition (DED) Additive Manufacturing (AM) using a multiphysics approach. We use a combination of Heat Transfer in Fluids, Solid Mechanics and Laminar Flow physics to accurately simulate the DED process. The ... En savoir plus
Modeling of Iron Ore Reduction Above the Cohesive Zone of the Blast Furnace
The blast furnace shaft is a huge counter flow reactor in which heat and mass exchange play a significant role in its mathematical modelling. The heat exchange model is already available in COMSOL Multiphysics® via the Local Thermal Non-Equilibrium interface. This multiphysics coupling ... En savoir plus
Electrothermoplasmonic Flow in Gold Nanoparticle Suspensions
Efficient mixing and pumping of liquids at the microscale is a technology that is still to be optimized. The combination of an AC electric field with a small temperature gradient leads to a strong electrothermal flow that can be used for multiple purposes. Combining simulations and ... En savoir plus
