Internal combustion engine components have been a main research interest over many decades. The structural mechanics and dynamics of the piston rings has been a large focus of work in order to gain a greater understanding of the how the piston ring dynamics affect the piston ring. Piston rings are often coated to reduce the level of wear on the ring as they will suffer substantial levels of ...

The implementation of thermal insulation in old residential building walls could compromise the hygrothermal behavior of the construction, especially in summer time when it is placed inside. A bad installation of insulation could have consequences on the quality of indoor air conditions and on the health of the wall mostly during hot periods. Thus, the evaluation of heat and mass transfer ...

Schistosoma mansoni parasites affect million people worldwide. The intensity of the infection can be evaluated by the number of eggs present in the stool of an infected individual. The application of the traditional methods has been regarded as impractical in developing areas and there is a continuous search for new techniques. In face of this scenario, a new method of diagnosis was explored in ...

Sodium is used as a coolant in Fast Breeder Reactors. Eddy Current Flowmeter (ECFM) is used for measurement of sodium flow in the primary pump and at the outlet of the subassemblies. Eddy Current Flowmeter (ECFM) works on the principle of change in the magnetic field profile due to induced eddy currents as a result of sodium flow. It consists of a central primary winding, energized from an A.C. ...

In this paper a finite element method(FEM) study of a surface acoustic wave (SAW)device excited by electrostatic coupling method is performed by using COMSOL Multiphysics. We have modeled a Rayleigh wave type SAW device by choosing YZ Lithium niobate as the substrate. The effect of external radio frequency (RF) field to the SAW device is analyzed. The effect of distance between the contactless ...

A micromirror or a torsional actuator in general has been proven to be one of the most popular actuators fabricated by Micro-Electro-Mechanical System (MEMS) technology in many industrial and biomedical applications such as RF switches, a laser scanning display, an optical switch matrix, and biomedical image systems. In this paper, two stacked micromirrors are presented and analyzed to show ...

Transport phenomena in spatially periodic magnetic systems, in particular the directed transport of magnetic beads in a so called magnetic ratchet (Brownian motor) are considered. Simulations are carried out to test and optimize this system, where the Smoluchowski equation with flux terms for the magnetic and gravitational force is used. Furthermore, experiments are carried out to verify the ...

Continuous dynamic models, e.g. COMSOL based simulations, play – besides statistical or iterative methods – a mayor role in theoretical ecology; in forecasting and management, but also in systems analysis. Ecological issues generally comprise highly interacting agents and/or unknown side effects. Here we show how combining direct simulation with COMSOL with simple optimization tools ...

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 ...

This paper presents an important step in developing a combined active noise- and audio system for a light jet. To prepare its installation both a wooden mock-up and a finite element model of the investigated cavity were created. Sensitivity analysis and key parameters selection were done in order to validate the model. Error analysis between measured and computed data closes the ...
