Novel class of artificial optical antennas are of great interest in biosensing applications of nanoplasmonics due to their unique and tunable spectral properties. Silver colloid spheres covered with L-cysteine were studied experimentally by spectroscopy and TEM and numerically by a COMSOL Multiphysics® simulation. Experimental studies revealed that the Ag NP-Cys core-shell conjugates prefer to ...

Capacitive energy extraction based on double layer expansion (CDLE) is a new method devised for extracting energy from the exchange of fresh and salty water in porous electrodes. First suggested by D. Brogioli, it is enclosed in a group of emergent technologies jointly known as Capmix methods. The CDLE technique is based on the fact that the capacitance of the electric double layer (EDL) ...

One can hardly get the exact analytic solution of a full time-dependent convection-diffusion equation, for describing the dynamics of a non-premixed flamelet. The analytic solution of the linearized form with such a model was studied by MATLAB®. And also, a numerical computation was made with the linearization model in COMSOL Multiphysics® software, to provide a perfect accordance with the ...

Continuous dynamic models, e.g. COMSOL based simulations, play – besides statistical or iterative methods – a mayor role in theoretical ecology; in forecasting and management, but also in systems analysis. Ecological issues generally comprise highly interacting agents and/or unknown side effects. Here we show how combining direct simulation with COMSOL with simple optimization tools ...

The importance of laser processing and thermal properties investigation of bulk materials and thin layers is still increasing. For thermal properties investigation many experimental systems were developed based on the photothermal effect. One of typical ways is to induce a rapid surface temperature increase is to use a pulsed laser beam, create a simplified model of this interaction, and compare ...

Chaotic systems may lead to instability, extreme sensitivity and performance reduction. Therefore it is unwanted in many cases. Due to these undesirable characteristics of chaos in practical systems, it is important to recognize such a chaotic behavior. The existence of chaos has been discovered in several areas during the last 30 years. However, there is a lack of studies in relation with ...

The paper demonstrates that for some models a 2D geometry in Cartesian coordinates can be used to obtain a 3D solution with changes in z-direction. A heat exchanger serves as an example of a practical application. The required flow rate in a straight cooling pipe penetrating perpendicularly into a warm wall is calculated to keep the wall temperature below a given limit. Cold water pumped into ...

The Swedish Nuclear Fuel and Waste Management Co (SKB) is responsible for final disposal of spent fuel and radioactive waste. SKB operates SFR, an underground waste repository in crystalline rock. The evolution of groundwater flow within the repository needs to be estimated considering different options for the design of the engineered barriers. The goal is to predict the effects of flow and ...

LiveLink™ for MATLAB® is used to fit the surface temperature of a battery cell within a COMSOL Multiphysics® model to the temperature measured by a thermal imaging camera. The test bench was designed and built up of ourselves to allow nondestructive thermal diffusivity measurement of Li Ion cells as a function of temperature, state of charge (SOC), state of health (SOH) and others. In that way ...
Extending Engineering Simulations to Scientists: Food Safety and Quality Prediction Using COMSOL Multiphysics® and LiveLink™ for Excel®

The objective of this study was to develop an easy to use interface in Excel® that connects to not only the solvers in COMSOL Multiphysics®, but also existing databases of food properties, foodborne pathogenic microorganisms kinetics, and chemical kinetics, creating a comprehensive simulation software to predict food safety and quality. The user interface allows the user to select the food, ...
