An investigation was undertaken into the suitability of using COMSOL for modeling an aircraft capacitive fuel gauging unit. A model of a sensor immersed in a fluid was developed for rectangular tank geometry with a range of fluid levels and sensor orientation using the electrostatics application mode in COMSOL’s AC/DC module The importance of modeling the capacitance of air was demonstrated. ...

This work analyzes the spin-diffusion dominated explanation for spin-up bulk flows in ferrofluid filled cylinders, with no free surface, subjected to a uniform rotating magnetic field. COMSOL results are compared to experimental results and analytical results. Simulating ferrofluid spin-up flows have many subtleties, especially when using a single domain region to model the ferrofluid ...

This paper gives an introduction to a continuing study detailing the process and development of using both experimental and Finite Element Analysis to characterise the acoustic response of a Carbon Fiber Reinforced Plastic (CFRP) laminate plate provided by a guitar manufacturer. The results show that there is a strong correlation between both the experimental and simulated data which gives ...

The design challenge for thermostimulation equipment is to get a combination of high electric field strength and high temperature within the muscle tissue without causing pain or skin burns. In the present work, COMSOL Multiphysics is used to simulate the temperature distribution and electric field distribution within body tissue for varying body composition and varying design parameters of the ...

This paper describes the development of a COMSOL model of Electro-Chemical-Mechanical Planarization (ECMP) that was validated with experimental data. ECMP is used for processing of semiconductor wafers. We developed a 2D model of flow of phosphoric acid solution (the electrolyte) between two parallel plates that focuses on the physics and electrochemistry in ECMP. The model includes steady-state ...

The MEMS microphone is also called microphone chip or silicon microphone.The pressure sensitive diaphragm is etched directly into a silicon chip by MEMS techniques and is usually accompanied with integrated preamplifier. Most MEMS microphones are variants of the condenser microphone design. The device consists of a polysilicon diaphragm suspended over a single crystal silicon backplate ...

Although resuscitation during pregnancy is relatively uncommon and rarely causes death, they have a particularly large impact in terms of the mortality of the unborn child and long-term effects on families and society as whole. In this paper, we present a new 3D finite element model of a pregnant female torso which accounts for presence of amniotic liquid and calculate current density ...

A 3D model was developed using COMSOL Multiphysics® to study the flow dynamics of the water inside the geometry of the [13N] Ammonia target for medical application . The image attached shows a 3D model of the target. A significant improvement was noted after modifying the geometry as suggested by the model and delivery time of radioactive solution was dramatically reduced. Water and aluminum ...

The self-ignition of tetrafluoroethylene (TFE) caused by contact with hot surfaces has been analyzed with the help of simulations performed with COMSOL Multiphysics®. The current study focuses on large-scale heated reactors for the industrial production of polytetrafluoroethylene (PTFE) from TFE at high pressures. Simulations of the self-heating and consequent self-ignition of TFE in a 100-dm3 ...

High temperature processes are used in a large variety of industrial application. Simulation helps to solve technological problems and increase energy efficiency in case of industrial scale simulation. We present in this paper a research equipment simulation. The aim is to increase knowledge of temperature field in the crystal growth region in order to give researcher some important information ...
