Energy harvesting from a fluid flow using piezoelectric materials is a relatively recent topic that has been investigated experimentally and numerically [1, 2]. Its possible application in natural water currents represents an interesting strategy to easily harvest renewable energy from ... 詳細を見る

Manufacture of complex micro-scale parts such as biomedical devices and micro tools that require an excellent surface finish has required non-conventional manufacturing processes such as pulsed electrochemical machining (PECM). Additional reverse polarity pulses make the PECM bipolar ... 詳細を見る

Eddy current testing (ECT) is widely used to check the integrity of electrically conducting parts and notably to detect flaws. It is based on the interaction between a probe and the part under testing. The finite element method (FEM) is well fitted to the modelling of these kinds of ... 詳細を見る

COMSOL Multiphysics was used to simulate the heat flux from battery cells via conjugate heat transfer physics which consist of laminar flow and heat transfer in solids and fluids. Laminar flow function was used to simulate natural convection of air within the sealed enclosure. Heat ... 詳細を見る

The Thomson coil’s (TC) inherent characteristics are appropriate to meet the needs of high speed actuators for mechanical switching devices in so-called smart grids. This is due to the massive forces that it can exert in the time scale of milliseconds. A coupled COMSOL Multiphysics model ... 詳細を見る

The purpose of this study is to predict, with a multiphysics model, the degradation area of a composite material when a current is injected into the material. The main physical phenomenon is an exothermic reaction, with an irreversible nonlinear variation of the electrical conductivity. ... 詳細を見る

A Helmholtz resonator type acoustic sensor has been designed using analytical method and finite element modeling software, COMSOL Multiphysics®. The acoustic sensor is an aluminium double frustum, hour glass, shaped with the resonator at the bottom and an acoustic horn above to amplify ... 詳細を見る

Patch antennas are widely used in communications links with unmanned aerial vehicles. Their hemispherical send and receive patterns enable the systems to maintain radio frequency contact over a wide range of vehicular attitudes. A microstrip-fed design offers other attractive features ... 詳細を見る

A piezoelectric transformer allows purely mechanical transfer and scaling of electrical energy via simultaneous utilization of both the direct and converse piezoelectric effects. This mechanical energy transfer enables a wide range of functional differences from typical magnetic-based ... 詳細を見る
