The Application Gallery features COMSOL Multiphysics® tutorial and demo app files pertinent to the electrical, structural, acoustics, fluid, heat, and chemical disciplines. You can use these examples as a starting point for your own simulation work by downloading the tutorial model or demo app file and its accompanying instructions.
Search for tutorials and apps relevant to your area of expertise via the Quick Search feature. To download the MPH-files, log in or create a COMSOL Access account that is associated with a valid COMSOL license. Note that many of the examples featured here can also be accessed via the Application Libraries that are built into the COMSOL Multiphysics® software and available from the File menu.
This tutorial model presents a study of a coaxial DC corona discharge in dry air at atmospheric pressure. The dimensions and operation conditions are similar to ones found in electrostatic precipitators with wire-to-plate configurations. The inner wire electrode has a 100-mm radius and ... Read More
This model simulates a negative corona discharge occurring in between two co-axially fashioned conductors. The negative electric potential is applied to the inner conductor and the exterior conductor is grounded. The modeled discharge is simulated in argon at atmospheric pressure. Read More
This application can be used as a design tool to develop an optimized battery configuration for a specific application. The app computes the capacity, energy efficiency, heat generation and capacity losses due to parasitic reactions of a lithium-ion battery for a specific load cycle. ... Read More
Diffusion-induced stress in lithium-ion battery electrode materials can occur as a result of compositional inhomogeneities during lithium intercalation in the host material particles. These stresses are important since the electrode host material can undergo significant volume changes ... Read More
This application models a DC glow discharge. The electron energy distribution function (EEDF) and electron transport properties are computed with the *Boltzmann Equation, Two-Term Approximation* interface. Since input parameters for the *Boltzmann Equation, Two-Term Approximation* ... Read More
This model simulates the discharge of a Nickel-Metal Hydride (NiMH) battery using the Battery with Binary Electrolyte interface. The geometry is in one dimension and the model is isothermal. The model serves as an introduction to NiMH modeling, and can be further extended to include ... Read More
This tutorial digs deeper into the investigation of rate capability in a battery and shows how the *Lithium-Ion Battery* interface is an excellent modeling tool for doing this. The rate capability is studied in terms of polarization (voltage loss) or the internal resistance causing this ... Read More
Due to the large differences in length scales in a lithium-ion battery, with the thickness of the different layers typically being several orders of magnitude smaller than the extension in the sheet direction, a lithium-ion battery is often well represented by a one-dimensional model. ... Read More
This model simulates electrical breakdown in an atmospheric pressure gas. Modeling dielectric barrier discharges in more than one dimension is possible, but the results can be difficult to interpret because of the amount of competing physics in the problem. In this simple model the ... Read More
Rechargeable lithium-air batteries have recently attracted great interest mainly due to their high energy density. The theoretical value is about 11400 Wh/kg which is around 10 times greater than the lithium-ion batteries. In this tutorial, discharge of a lithium-air battery is ... Read More
