Describing and predicting the extent of the physicochemical processes as well as geometrical deformation taking place during food transformation is of major importance to control food functional properties. Unfortunately, only a few food-matrix models consider deformation particularly because of large deformation. In the case of a starchy product such as rice, water transport and swelling ...

Joule heating is simulated in COMSOL Multiphysics® software for the electro-thermal micro actuator. The aim is to choose the optimal design parameters to get the largest possible in-plane displacement. The comparison between the different possible configurations will reveal the optimal parameters for the longest displacement. Our current micro fabrication process allows the actuator to use ...

This poster showcases a fully parametric, nonlinear, time-dependent polyethylene (PE) pipe squeeze-off model that was developed in COMSOL Mulitphysics® software by the Gas Technology Institute (GTI) and Veryst Engineering, and sponsored by Operations Technology Development (OTD). Utilizing the Nonlinear Structural Materials Module and a custom viscoelastic-plastic constitutive model developed ...

The U.S. Army Corps of Engineers is currently investigating the use of infrasound sensors to monitor the health of structures of interest. Infrasound is low-frequency (2-20 Hz) acoustic energy and is capable of propagating many kilometers from the source structure. Large infrastructure, such as dams, bridges, and buildings emit such signals at their natural or driven frequencies of vibration, ...

In addition to using advanced functions built-into the engine of the COMSOL Multiphysics® software, we integrate dynamic properties of rotating components that are measured or pre-computed. Here, it is shown how to integrate fluid-film characteristics and take advantage of post-processing and graphics to present the results to the customers using the Cloud. COMSOL® simulations of rotor-bearing ...

The pH-sensitive hydrogels are responsive to the pH of surrounding solution, which often resemble to biomaterials. Recently, pH-sensitive hydrogels are widely used in various devices as sensing media. We present the simulation of swelling characteristic of 3D-arbitarary-geometry, pH-sensitive hydrogel in steady state conditions. Three nonlinear partial-differential equations that are ...

To reduce friction in lubricated tribological contacts, the surfaces of the contacting bodies can be microstructured to improve lubricating conditions. For lower loaded contacts this approach has already reached industrial applications, e.g. the piston-liner contact. For higher loaded contacts the effects are currently in basic research. Elastic deformation in the contact area plays an important ...

Nowadays, to go along with sustainable development and for cost matters, automotive heat exchangers are built with less and less aluminum and the process costs are being cut. However, the real mechanical response is a plastic shakedown, which is why we need to model the cyclic response as well as to find a fatigue criterion. A finite element model was developed using COMSOL Multiphysics to ...

This paper addresses the study of thermal behavior of thermoset polymer matrix filled with microparticles. A numerical model was developed with COMSOL Multiphysics to get a random spatial distribution of fillers in a representative volume element (RVE). This model was then compared to an analytical reference model (Hamilton model) and experimental results. This comparison highlights a good ...

Over the last decade, plasmonic nanoparticles (PNPs) have received growing interest as exogenous contrast agents in the thermal expansion based photoacoustic (PA) imaging technique in biomedical applications . Such functionality is due to the localized surface plasmon resonance (LSPR) created by the light-induced coherent oscillation of the conduction electrons in the PNPs. In the near-field ...
