This example illustrates how to set up and solve a tank-in-series model in 0D using the Reaction Engineering interface. The model treats a series of three consecutive tank reactors. A feedback loop continuously adjusts the inlet concentration of the first tank to keep the concentration ... Mehr lesen
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 ... Mehr lesen
This example investigates the electrical and thermal characteristics of a welding argon arc created in a point-to-plane configuration. The discharge is assumed to be in local thermodynamic equilibrium. The electric arc is considered a conductive fluid medium and is modeled using a ... Mehr lesen
This tutorial model compares the results between a domain approach and the Thin Moisture Barrier feature to simulate the moisture transport in a wall with a vapor barrier. The Thin Moisture Barrier feature neglects diffusion, two studies are proposed, a first one where diffusion is ... Mehr lesen
This model simulates the propagation of a positive streamer in a weak electric field where the process of photoionization is essential to provide seed electrons at the front of the streamer head. The simulated electric field and electron density as a function of time agree well with that ... Mehr lesen
A catalyst particle with a hypothetical microstructure is described in detail. The heterogeneous description is approximated in a second model with a homogeneous particle and the results from the two approaches are compared. See: https://www.comsol.se/blogs/modeling-approaches-in ... Mehr lesen
The electrical insulation strength of gases is generally much lower than that of solids. Under normal operating conditions, electrical discharges—known as partial discharges—can occur in voids or cracks within a solid dielectric. This model simulates partial discharges in a spherical ... Mehr lesen
This example demonstrates how to couple the Lithium-ion Battery interface to the Phase Field interface for modeling electrode deformations. The example is based on the Lithium Plating with Deformation model, available in the Battery Design Module Application Library. As current is ... Mehr lesen
This model illustrates the modeling of slider motion caused by a base rotation. The motion of the slider is analyzed under various forces such as inertia force, centrifugal force, spring force and damping force. The prismatic joint, which is used to connect the two components, is spring ... Mehr lesen
This model demonstrates two approaches to model the acoustics in a generic nacelle with an acoustic liner and a background flow. The first method uses the Compressible Potential Flow and the Linearized Potential Flow, Frequency Domain interfaces, while the second, more detailed approach, ... Mehr lesen
