This model simulates the mixing of two types of grains in a rotating drum with baffles. The effect of the number of baffles on the mixing is demonstrated by varying the number of baffles in the drum. This model also demonstrates how to build and run a model method that evaluates the ... En savoir plus
A trimmer capacitor has a variable capacitance. One way of obtaining this is to use parallel facing electrodes with a variable overlap area. In this example, the capacitance can be changed by turning one electrode using a screwdriver. Typically a linear angular response is desired. ... En savoir plus
These two example models demonstrate how state variables (new in COMSOL Multiphysics® version 5.5) can be used to define and use history-dependent variables. Learn more in the accompanying blog post: "How to Use State Variables in COMSOL Multiphysics®" En savoir plus
This example simulates Trichel pulses produced by negative corona discharge under a point-to-plate configuration. The electron density and the electric field are obtained, as well as the discharge current. The discharge current clearly shows the pulsating characters. Each current pulse ... En savoir plus
This model demonstrates how to find the optimal size and position of a water pipe in an air chamber, so that the energy absorption in the water is maximized. The objective is implemented as a constraint, so that the optimization terminates, when the desired performance is achieved. En savoir plus
Active aerodynamics systems actuate components on a vehicle dynamically to improve fuel efficiency, optimize cooling, and enhance stability. A drag reduction system (DRS) is an example of an active aerodynamic technology, which is often used in Formula 1® cars to overtake other cars ... En savoir plus
This model compares the numerical and analytical solutions for the capacitance matrix of two non-concentric spheres. It also illustrates the relation between the Maxwell capacitance matrix and the mutual capacitance matrix. Learn more about this model in the blog post "How to Calculate ... En savoir plus
In microfluidic devices, it is a challenge to mix different fluids. One method is to use acoustic streaming to create a flow which enhances the mixing of two fluids. In this model, the vibrations of PDMS structures in a channel induces fast acoustic streaming used for mixing a diluted ... En savoir plus
This model illustrates the working principle of an axial homopolar induction bearing. An electrically conducting rotor rotating in a magnetic field produced by a permanent magnets induces eddy currents on the conducting rotor. The eddy currents, in turn, produce a magnetic field that ... En savoir plus
This model utilizes a continuation solver to efficiently compute the current–voltage characteristics of a corona discharge generated by a wire-to-wire configuration. It provides a flexible framework that can be easily adapted to study other discharge configurations and types. En savoir plus
