Dental restorations can be made by different materials bonded together, which grant good mechanical resistance and aesthetic at the same time. In order to evaluate the behavior of dental restorations in the oral environment, a test, called thermocycler, is used, which simulates the temperature changes and the chemical environment of the mouth. The objective of this work is to evaluate thermal ...

We have created and optimized a multiphysics model using COMSOL Multiphysics® software that incorporates the Free and Porous Media Flow and Heat Transfer in Porous Media interfaces to simulate the temperature profile of a chromatographic system under external heating and cooling conditions. In chromatography, a liquid mobile phase is pumped through a column containing a stationary phase made ...

The DUNE experiment (http://www.dunescience.org/) is an international collaboration of more than 100 research institutes and universities (among them CERN and Fermilab) which is taking the challenge of building the next-generation experiment for the study of neutrino particles. The detector conceived to detect neutrinos consists of a gigantic cryogenic apparatus able to keep 700,000 tons of ...

Microwave heating is known for its efficiency and instantaneity. However, the non-uniformity of the microwave heating has limited the development of its application in industry. In order to solve this problem, a metal patch sticking to the turntable was proposed. During the heating process, the location of the metal patch will change along with the rotation of turntable. Thus, regulate the ...

Acoustic wave propagation due to the breakage or slippage of reinforced wire in water-filled prestressed concrete cylinder pipe (PCCP) attracts interest in non-destructive pipe testing. Current practice of acoustic emission (AE) detection and wire-break related events (WRE) recognition is based on field data analysis. This work deals with the theoretical investigation of WRE signal from ...

The results of two thermal response tests recently performed on two vertical borehole heat exchangers (BHEs) are presented. The BHEs have the same cross section and a depth of 100 m and 120 m respectively. The evaluation of the thermal properties of the ground and grout are performed by a finite-element simulation method, developed through the software package COMSOL Multiphysics 3.4.

Finite Element analysis is used to model 2-D and 3-D paraelectric-dielectric composites (BaTiO3 spherical fillers randomly distributed in constant dielectric matrix). The effective dielectric response and tunability are studied under different filler sizes and different volume fractions. The results are consistent with previous theoretical and experimental results: with the increasing of filler ...

In this study, numerical simulations of mixing in turbulent flow, subject to a change in density, are performed. Attention is focused on the binary mixing between two streams of fluid in which a variable density step are formed due to a difference in the temperature. This binary mixing problem performed by assuming low Mach number flow. The results demonstrate the variable density effects and ...

During cryopreservation of human embryos, ice crystal formation in the embryos or in surrounding media may cause cryodamage to them and can be lethal. A strategy to avoid this is the vitrification procedure when the embryo and the surrounding medium undergo the transition to glassy state rather than a crystalline one during cooling. Similarly, recrystallization in the embryo or the medium must ...

This paper presents the use of the multiphysics package COMSOL for teaching heat and moisture transport modeling in the research area of building physics. It includes a description on how COMSOL works and six exercises with 2D, 3D, steady state and transient models. It is concluded that COMSOL is a very useful tool for this kind of engineering education. Especially, the abstraction level of ...
