Einer der gängigsten Reaktoren in der chemischen Industrie für den Einsatz in heterogenen katalytischen Prozessen ist der Festbettreaktor. Dieser Reaktortyp wird sowohl bei der Synthese als auch bei der Abwasserbehandlung und der katalytischen Verbrennung eingesetzt. Dieses Modell ist ... Mehr lesen
The Cathodic Protection Designer application is an example of how an application can be used to simplify the simulation process by featuring a way to import a generic CAD file with certain requirements. Using this app, the user can select each part of the geometry and set boundary ... Mehr lesen
This example solves for the temperature distribution inside a vacuum flask holding hot coffee. The main purpose is to illustrate how to use MATLAB functions to define material properties and boundary conditions. Mehr lesen
Power inductors are a central part of many low-frequency power applications. They are, for example, used in the switched power supply for the motherboard and all other components in a computer. Computer simulations are necessary in the design of such inductors. This model calculates the ... Mehr lesen
A Biconical antenna is a type of wideband antenna with omni-directional radiation pattern in the H-plane similar to a dipole antenna. A coaxial feed is connected to the radiators using two 90 degree bent arms. The model shows that the biconical antenna works well in applications ... Mehr lesen
For a description of this model, see our accompanying blog post "Can COMSOL Multiphysics® Solve the Hydrogen Atom?". Mehr lesen
Light rail transit (LRT) systems often utilize DC power for train propulsion. In these systems the potential gradients in the rails may induce stray currents, which corrode adjacent metallic structures. In this example, the Cathodic Protection interface, using Edge Electrode nodes, is ... Mehr lesen
In small PEM fuel cell systems (in the sub-100 W range) no active devices for cooling or air transport are normally used. This is due to the desire to minimize parasitic power losses from pumps and fans, and to reduce the system complexity, size, and cost. The reactants at the cathode ... Mehr lesen
This model calculates the DC characteristics of a simple MOSFET. The drain current versus gate voltage characteristics are first computed in order to determine the threshold voltage for the device. Then the drain current vs drain voltage characteristics are computed for several gate ... Mehr lesen
Sensitivity analysis is an efficient way of computing the gradient of an objective function with respect to many control variables. This example uses the pitch and yaw in the top of a truss tower as objective functions. It shows how to compute the sensitivity of these angles with respect ... Mehr lesen
