Abstract: Due to the restriction of the number of probes that a patient can tolerate, and the inaccurate information provided by the invasive temperature measurements, which provide information only at discrete points, a mathematical model simulation is more effective to help doctors in planning their thermal treatment doses. This will maximize therapeutic effects while minimizing side effects. ...

COMSOL Multiphysics® has standard facilities to export models to SimuLink®. Normally, the standard export works well if the solvers, available in SimuLink, can handle the problem. However, if a model in COMSOL Multiphysics® needs special solvers, for example airflow or other non-linear problems, the standard export to SimuLink is often not suitable, because the standard solvers of SimuLink® ...

Borehole heat exchangers (BHE) in connection with heat pumps and floor heating in many countries are becoming an alternative to conventional heating or cooling systems using fossil resources. We describe how 1D components for heat transport in pipes can be coupled with a 2D or 3D component for the ground. Thermal conductances are derived for laminar, transitory and turbulent flow conditions in ...

COMSOL Multiphysics was used to design a binocular load cell. A three-dimensional linear solid model of the load cell spring element was studied to quantify the high-strain regions under loading conditions. The load cell was fabricated from 6061 aluminum, and general purpose Constantin alloy strain gages were installed at the four high-strain regions of the spring element. The four gages were ...

The conductivity of seawater directly correlates with the concentration of dissolved salts. This model demonstrates a new approach to the methodology of inductive conductivity measurement of seawater and other liquids. COMSOL Multiphysics® was used to build a parametrically swept model of an O-Core Inductive Conductivity Measurement Sensor for Seawater. This sensor model is built using the ...

Conventional swing is one phenomenon which a bowler uses to gain an advantage over the batsman. This study involved simulating conventional swing in the CFD Module of COMSOL Multiphysics® software and comparing the simulated results with experimental results of previous researchers. The variation in the side and drag forces on the ball were investigated by varying the velocity, seam angle and ...

Numerical theory provides the basis for quantification of the accuracy and reliability of a FEM solution by error estimates on the FEM error vs. the mesh spacing of the FEM mesh. This paper presents techniques needed in COMSOL Multiphysics® software to perform computational studies for elliptic test problems in two and three space dimensions that demonstrate this theory by computing the ...

In this study, a capability has been developed for modeling the linear viscoelastic behaviour of a glassy polymer using COMSOL Multiphysics®. The two rheological models by Maxwell and Kelvin-Voigt were used for modeling stress relaxation and creep loading behavior, respectively, of a typical gas pipe under two modes of plane stress and plane strain. An advantage of the developed model is its ...

High Pressure Processing (HPP) is a leading non-thermal food processing technology that is often cited as a major technological innovation in food preservation. Although it is very early to place this emerging technology among the list of breakthroughs in food processing, HPP has started to become a viable commercial alternative for pasteurisation of value added fruits, vegetables, meat, and ...

Energy harvesting from ambient vibrations has become an interesting topic for powering wireless sensor networks. Resonant microdevices based on MEMS have become of central importance at low frequency. The power produced at resonance is at least one order of magnitude larger than off frequency power since the largest strain is obtained at resonance. In order to obtain large strain for efficient ...
