Two Anode Surface processes are examined : Formation of Solid Electrolyte Interphase (SEI) and heating due to Shuttle Current. During charging, higher order sulfur species are reduced at the anode surface, while they are concurrently being oxidized at the cathode. This leads to the formation of a parasitic ‘shuttle’ current. We show that heating due to this shuttle current can lead to large ...

Different types of technologies to recycle carbon fiber reinforced polymer (CFRP) waste have been studied, for example: pyrolysis, solvolysis and steam-thermolysis. The steam-thermolysis is a process that combines pyrolysis and superheated steam at atmospheric pressure to decompose the organic matrix of the composite. The waste is introduced into a bench-scale reactor heated at high temperatures ...

In the production of high quality materials by a heat treatment, it is indispensable to accurately predict the temperature inside the furnaces being employed. In this work we develop a turbulent combustion model for the heat being released by gas burners inside a shaft kiln. Turbulent combustion is the strongly coupled phenomena of the chemically reacting fuel and oxygen in a turbulent flow. ...

Ionic polymer-metal composite (IPMC) materials are promising candidates for soft robotics and artificial muscle applications. The primary actuation mechanism in such devices is ion migration in a polymer membrane, localized swelling, and a corresponding overall material deformation, which is multiphysics in nature. Simulations were performed for a rectangular IPMC actuator in response to a ...

Comprehensive studies of drug transport in nanofibres based mats have been performed to predict drug release kinetics. The paper presents our approach to analyze the impact of fibers arrangement, one of the parameters varied in our parallel experimental studies. COMSOL Multiphysics® has been used to assess the impact of the various purposed arrangements of fibers within the mat. Drug release ...

In this work we report a numerical model of a Rotating Disk Electrode (RDE) voltammetry in a finite size domain. Thus, explaining the discrepancy of the diffusion coefficient obtained from the experimental rotating speed, with respect to the literature data. We achieved a very good agreement at the limiting current and at the unexpected peak for the RDE voltammetry at 2000 rpm and different ...

Understanding the air flow patterns and aerosol trajectories in ventilated rooms can provide key information for determining where to place early warning and monitoring instruments, and how to minimize hazardous materials in the worker’s breathing zone. The dispersion within rooms can be influenced by complex interactions between numerous variables, but especially ventilation design and room ...

COMSOL Multiphysics® software was used in this study to simulate mixing by diffusion and by secondary flow. Particle tracing model was applied to simulate the mixing of cells in the microchannel. Results agreed well with the measurement, an optimal herring-bone structure was proposed for integration into a bioanalytical system.

During the hydraulic fracturing process, there can be possible re-activation of closed/sealed faults and natural fractures in the formation, which may lead to changes in the boundary conditions of the reservoir. While study models of shale gas formations have utilized the concept of a closed reservoir in order to optimize the production of gas in the well-bore, this assumption cannot be adopted ...
