Puffing of biomaterials involves mass, momentum and energy transport along with large volumetric expansion of the material. Development of physics-based models that can describe heat and moisture transport, rapid evaporation and large deformations can help understand the puffing process. In this context, a fundamentals based study of salt-assisted puffing of rice is described. A multiphase model ...

Adaptive Optics is common sense, since many people use digital cameras with electromechanical iris actors on elastic autofocus lenses. This project tries to create a COMSOL Multiphysics based mathematical model of adaptive optics with electrostatically induced deformation of dielectric gels. Upper and lower sides of a lens (dielectric conductive gel) are coated by transparent conductive films, i ...

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 ...

The subject of the study is a bespoke rainscreen system designed for the Grand Theatre of Rabat, Morocco (Figure 1). The project presents a complex façade geometry and consists of a 1800-seat theater, an open-air amphitheater with a capacity of 7000 people, a rehearsal space and a restaurant. The rainscreen system consists of fiberglass individually cast reinforced concrete (GRC) panels ...

Mechanical product design is crucial in many engineering field and lots of industries. CAE simulation has been widely applied for predicting virtual product design for a few decades to reduce the cost and shorten the design life cycle. Because of complicated geometry, material/geometrical nonlinearity and complex conditions, it is painful to efficiently and accurately simulate and predict ...

This paper reports the structural solid mechanic simulation of a MEMS out-of-plane platform that provides thermal and electrical isolation for a device built on it. When assemble, the platform lifted for approximately 400 μm above the substrate level. A mechanical stress analysis is then presented in order to evaluate the feasibility of building it using commonly used materials in MEMS. Our ...

Manual wheelchair users suffer shoulder pain and injury in the long term because of unconscious overuse. The ‘SENSEWHEEL’, which interposes three identical load cells between pushrim and rear wheel, measures the three components of pushing force Fx, Fy and Fz, and axial torque Tx applied at each load cell. Strain gauges were located on a diaphragm forming one face of the load cell. The ...

COMSOL Multiphysics® has been used to predict the magnetic fields, eddy current, lorenz forces and stresses during a disruption for the new Advanced Outer Divertor for the Alcator C-Mod tokamak. A tokamak is used to study magnetic confinement of plasma for fusion, and a disruption occurs when the plasma decays, rapidly losing all of its current. COMSOL has been used to recreate the fields ...

Engineering design studies of the feasibility of conversion of the High Flux Isotope Reactor (HFIR) from high-enriched uranium to low-enriched uranium fuel are ongoing at ORNL as part of an effort sponsored by the U.S. Global Threat Reduction Initiative program. HFIR is a very high flux, pressurized light-water-cooled and moderated, flux-trap type research reactor whose current missions are to ...

A growing demand is recently emerging of sensors to be integrated in the concrete in order to measure some critical parameters, such as humidity and temperature and the internal pressure of the material. For example, by monitoring the pressure in various strategic points of the structure and their evolutions over time it is possible to understand the health of the structure and the needs for ...
