Magnetic Field of a Helmholtz Coil

A Helmholtz coil is a parallel pair of identical circular coils spaced one radius apart and wound so that the current flows through both coils in the same direction. This winding results in a uniform magnetic field between the coils with the primary component parallel to the axes of the two coils. Applications of Helmholtz coils range from canceling the earth’s magnetic field to generating ...

Shell-and-Tube Heat Exchanger

Shell-and-tube heat exchangers are commonly used in oil refineries and other large chemical processes. In this model, two separated fluids at different temperatures flow through the heat exchanger, one through the tubes (tube side) and the other through the shell around the tubes (shell side). Several design parameters and operating conditions influence the optimal performance of a shell and ...

Flow Through a Pipe Elbow

Water flow in a 90 degree pipe elbow. The flow is simulated using the k-omega turbulence model. The result is compared to engineering correlations.

Transport and Adsorption

This model demonstrates how to model phenomena defined in different dimensions in a fully coupled manner using COMSOL Multiphysics. Whereas in most cases the reaction rate expression is defined as a function of the concentrations of the reactants and products, in adsorption reactions it is also necessary to model the surface concentrations of the active sites or surface complex. This implies ...

Evaporative Cooling of Water

This tutorial shows how to couple three physics interfaces to model evaporative cooling. The effects that need to be taken into account are heat transfer, transport of water vapor, and fluid flow. User-defined expressions are used to implement the source term for the water vapor and evaporative heat source as well as the moist air feature to accurately describe the material properties.

Using Meshing Sequences

COMSOL Multiphysics provides an interactive meshing environment where, with a few mouse clicks, you can easily mesh individual faces or domains. Each meshing operation is added to the meshing sequence. The final mesh is the result of building all the operations in the meshing sequence. This example demonstrates how to use the meshing sequence to create a mesh consisting of different element ...

Modeling of a 3D Inductor

Inductors are used in many applications for low pass filtering or for impedance matching of predominantly capacitive loads. They are used in a wide frequency range from near static up to several MHz. An inductor usually has a magnetic core to increase the inductance, while keeping its size small. The magnetic core also reduces the electromagnetic interference with other devices as the magnetic ...

Optical Scattering Off of a Gold Nanosphere

This model demonstrates the simulation of the scattering of a plane wave of light by a gold nanosphere. The scattering is computed for the optical frequency range over which gold can be modeled as a material with negative complex-valued permittivity. The far-field pattern and losses are computed.

Anisotropic Heat Transfer through Woven Carbon Fibers

This model and presentation shows how to model anisotropic properties of fibers in a heat transfer simulation. Because the fibers orientation is not easy to define explicitly, the curvilinear coordinate interface is used to define the fiber orientation. The fibers have high thermal conductivity in the fiber direction and low conductivity in the perpendicular direction.
