Polymerization in Multijet Tubular Reactor

In a polymerization reactor for polyester manufacturing, the mixing in the reactor is achieved by impinging turbulent jets of reactants onto each other. The turbulence affects the reaction kinetics and quality of the polymer linkage. Turbulent flows involving rapid reaction kinetics are quite common in the production of polymers, and the complex interplay between fluid dynamics and fast chemical ...

Pacemaker Electrode

This model, dealing with the current and potential distribution around one pair of electrodes, demonstrates how to synchronize and modify geometry in SolidWorks by using the LiveLink interface.

Molecular Flow Through an RF Coupler

This model computes the transmission probability through an RF coupler using both the angular coefficient method available in the Free Molecular Flow interface and a Monte Carlo method using the Mathematical Particle Tracing interface. The computed transmission probability determined by the two methods is in excellent agreement with less than a 1% difference. This model requires the Particle ...

Inflation of a Spherical Rubber Balloon - Membrane Version

The purpose of this model is to illustrate how the Membrane interface can be used to model thin hyperelastic structures. The example is identical to the Model Library model 'Inflation of a spherical rubber balloon', except that the Membrane interface is used instead of the Solid Mechanics interface.

Small Concert Hall Analyzer

Designing structures and open spaces with respect to sound quality is important for concert halls, outdoor environments, and even the rooms of a house. Simulating acoustics in the high-frequency limit, where the wavelength is smaller than the geometrical features, can be done with ray acoustics. This application analyzes the acoustics of a small concert hall using the Ray Acoustics physics ...

Thermal Microactuator Simplified

This example model consists of a two-hot-arm thermal actuator made of polysilicon. The actuator is activated through thermal expansion. The temperature increase required to deform the two hot arms, and thus displace the actuator, is obtained through Joule heating (resistive heating). The greater expansion of the hot arms, compared to the cold arm, causes a bending of the actuator. The material ...

Primary Creep Under Nonconstant Load

In this model example, you will study the creep behavior of material under non-constant loading. You will model the primary creep using a Norton-Bailey law and study the difference between the time hardening and the strain hardening methods available in COMSOL Multiphysics. The model is taken from NAFEMS Understanding Non-Linear Finite Analysis Through Illustrative Benchmarks. The load consist ...

Vibrating Plate in a 2D Viscous Parallel Plate Flow

This is a small 2D demonstration model that couples the linearized Navier-Stokes Frequency Domain, the Solid Mechanics, and the Creeping Flow physics interfaces to model the vibrations of a plate located in a 2D viscous parallel plate flow. This type of model is used to model fluid structure interaction (FSI) in the frequency domain. For simplicity the flow is assumed to be a Creeping flow. ...

Outgassing Pipes

This benchmark model computes the pressure in a system of outgassing pipes with a high aspect ratio. The results are compared with a 1D simulation and a Monte-Carlo simulation of the same system from the literature.

Electrical Heating in a Busbar

This tutorial model of the Joule heating effect in a busbar demonstrates how to synchronize an assembly between Inventor and COMSOL, how to modify the geometry from COMSOL, and how to run a geometric parametric sweep.
