Vibrating Beam in Fluid Flow

A classical flow pattern is the von Kármán vortex street that can form as fluid flows past an object. These vortices may induce vibrations in the object. This problem involves a fluid-structure interaction where the large deformation affect the flow path. The magnitude and the frequencies of the oscillation generated by the fluid around the structure is computed and compared with the values ...

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.

Bandgap Analysis of a Photonic Crystal

This model investigates the wave propagation in a photonic crystal that consists of GaAs pillars placed equidistant from each other. The distance between the pillars determines a relationship between the wave number and the frequency of the light, which prevents light of certain wavelengths propagating inside the crystal structure. This frequency range is called the photonic bandgap. There are ...

Voltage Induced in a Coil by a Moving Magnet

A magnet moving axially through the center of a coil will induce a voltage across the coil terminals. One practical application of this is in shaker flashlights, where the flashlight is vigorously shaken back and forth, causing a magnet to move through a multi-turn coil, which provides charge to the battery. In this model, the motion of a magnet through a coil is modeled, and the induced ...

Optical Scattering by Gold Nanospheres

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.

Parameterized Shell-and-Tube Heat Exchanger Geometry

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 ...

Axisymmetric Transient Heat Transfer

This is a benchmark model for an axisymmetric transient thermal analysis. The temperature on the boundaries changes from 0 degrees C to 1000 degrees C at the start of the simulation. The temperature at 190 s from the anlysis is compared with a NAFEMS benchmark solution.

Effective Diffusivity in Porous Materials

Transport through porous structures is usually treated using simplified homogeneous models with effective transport properties. This is in most cases a necessity, since the typical dimensions of the pores and particles making up the porous structure are several orders of magnitude smaller than the size of the domain that is to be modeled. This model introduces the concept of effective ...

Frequency Selective Surface, Periodic Complementary Split Ring Resonator

Frequency selective surfaces (FSS) are periodic structures with a bandpass or a bandstop frequency response. This model shows that only signals around the center frequency can pass through the periodic complimentary split ring resonator layer.


The purpose of the Mixer application is to provide a user-friendly interface where scientists, process designers, and process engineers can investigate the influence that vessels, impellers, baffles, and operating conditions have on the mixing efficiency and the power that is required to drive the impellers. You can use the app to understand and optimize the design and operation of a mixer for a ...
