This is the transient model of a single phase E-core transformer using a homogenized approach for the multi-turn primary and secondary coils. The model includes the effect of magnetic saturation (B-H curve) in the core and shows how to connect the transformer model to the external ... En savoir plus
Applying an electric field across a suspension of immiscible liquids may stimulate droplets of the same phase to coalesce. The method known as electrocoalescence has important applications, for instance, in the separation of oil from water. To model electrocoalescence, you need to solve ... En savoir plus
A piezoelectric transducer can be used either to transform an electric current to an acoustic pressure field or, the opposite, to produce an electric current from an acoustic field. These devices are generally useful for applications that require the generation of sound in air and ... En savoir plus
In this model, a rotor with permanent magnets and a nonlinear magnetic material rotates within a stator of the same magnetic material. The generated voltage in windings around the stator is calculated as a function of time. COMSOL Multiphysics models the rotation with assemblies and ... En savoir plus
Usually limited to a specific region, corona discharges appear as a consistent luminosity. The attributes of steady glow corona discharges change depending on their polarity. Positive glow corona, also referred to as Hermstein's glow or ultra corona, presents a direct current (DC) aspect ... En savoir plus
This tutorial example shows how to use the Electric Currents in Shells interface together with Magnetic Field interface to compute the resistance and inductance of a planar PCB coil in the stationary regime. En savoir plus
A tonpilz transducer is used for relatively low frequency, high power sound emission. It is one of the popular transducer configurations for SONAR applications. The transducer consists of piezoceramic rings stacked between a head mass and a tail mass which are connected by a central ... En savoir plus
This model demonstrates the analysis of lightning surges on high voltage transmission line towers. Lightning carrying a current of 10 kA struck one of the tower's shielded wires. The induced voltage at the three-phase conductors are computed. Some highlights of this model: Perform ... En savoir plus
This app demonstrates the following: Multiple tabs in the ribbon Geometry parts and parameterized geometries Parts and cumulative selections can be used to automatically set domain and boundary settings in the embedded model Adding or removing geometry parts with different geometrical ...
