Rotating Channel Benchmark

A lab-on-a-chip platform can be realized on a rotating disc by designing channels and other features to use the Coriolis or centrifugal forces to manipulate the flow. These forces are controlled by changing the angular velocity of the disc, so the platform is programmed by using a controlled sequence of angular velocities. In a microchannel, the centrifugal force induces a parabolic flow profile ...

Model of an Atmospheric Pressure Corona Discharge

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.

Plasma Display Panel

This model illustrates the physics of a dielectric barrier discharge which leads to generation of UV light. Such a discharge is used to generate the back light for plasma display panels.

Molecular Flow Through an S-bend

This model computes the transmission probability through an s-bend geometry 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 by the two methods is in excellent agreement with less than a 1% difference. This model requires the Particle Tracing ...

How to Use Contour Line in Geometry

This presentation gives instructions on how to export a Contour Plot (single line), re-import it as an Interpolation Curve on a Work Plane in the Geometry, extrude the Work Plane, then Convert to Solid to create two domains separated by the new surface.

Stress Analysis of an Elliptic Membrane

This is a benchmark model for a plane stress problem. The accuracy of the computed stress concentration is evaluated, and a mesh convergence study is performed for different element types.

Pacemaker Electrode, Modeled with LiveLink for Creo Parametric

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

Optimization of a Tuning Fork, Modeled with LiveLink for Pro/ENGINEER

This model computes the fundamental eigenfrequency and eigenmode for a tuning fork that is synchronized from Pro/ENGINEER via the LiveLink interface. The length of the fork is then optimized so that the tuning fork sounds the note A, 440 Hz.

Ion drift velocity calculation by direct Monte Carlo simulation

The drift velocity of Ar+ is calculated using a Monte Carlo simulation in which the elastic collisions of Argon ions with ambient neutrals are explicitly modeled. The model uses energy-dependent collision cross-section data from experiment. The average ion velocity values are consistent with experimental data over a wide range of reduced electric field magnitudes. This agreement suggests that ...
