Introduction: Existing solar cell (photovoltaic, PV) device simulation software is either open source with limited capabilities (1D only) [1,2] or extremely expensive with obscure functionality . PV researchers need an accessible and versatile simulation tool to optimize existing technologies and to reduce the time from concept to prototype for new technologies. This work demonstrates how ...

Capacitor is mainly defined as two conducting plates that can hold the opposite charges on it. These plates can be used either as a sensor or an actuator. If the relative distance between the two conductors changes as result of given input, then capacitance values will change. This results in basic of capacitive or electrostatic sensing configuration. On the other hand, if a voltage or the ...

Induction motors, as any other industrial products, have to comply with various requirements on noise levels. Therefore, it is essential to use an appropriate prediction tool to verify and optimize the design of an induction motor with respect to the acoustic performances. The paper will focus on the prediction of the magnetic noise generated and radiated by a specific motor. The challenge is ...

The work proposed in this paper deals with the consideration of 3D geometric effects to evaluate the iron losses in magnetic devices used in power electronics. To carry out this work, we rely upon two existing models of iron losses per unit volume calculation ("Steinmetz") currently used in power electronics. We coupled these two models with a finite element magnetic field calculation software, ...

The electric field plays a very important role in the electrospinning process, which needs to be seriously considered in the electrospinning configuration developing. High voltage involved in electrospinning process leads to difficulty in measuring the electric field. Numerical simulation is used to design the electric field, and experiments are carried out to validate the spinneret and ...

Lubricant oil is used to ensure proper functioning of industrial machinery such as turbines, gears, bearings and compressors. Oil analysis is used to detect and quantify the presence of wear metals and other contaminants in the lubricant of oil wetted systems, by sensing the change in relative permittivity of the oil as the wear metals pass through capacitor electrodes. Three configurations of ...

Plasma torches are used in processing of materials as well as in the energy industry for producing plasma. In a non-transferred arc plasma torch, an electric arc can be initiated by applying a direct current (DC) between the cathode and anode, both placed inside the torch. Then, the plasma is obtained by heating, ionizing and expanding a working gas, introduced into the chamber of the torch ...

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 ...
