An ultrasonic standing wave levitator, also called acoustic levitator, is a device used for levitating fluid and solid particles in an acoustic field. The standing acoustic waves exert an acoustic radiation force on the particles. The force is a second order effect and stems from a ... Mehr lesen
This model demonstrates the path of relativistic protons within Earth's magnetic field. Due to the dipole nature of Earth's magnetic field, charged particles, such as electrons and protons, can get trapped in stable configurations within it for long periods of time. These ... Mehr lesen
Space charge limited emission is a phenomenon that restricts the current of charged particles that can be released from a surface. As the electron current released by a cathode increases, so does the magnitude of the charge density in the immediate vicinity of the cathode. This ... Mehr lesen
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 ... Mehr lesen
Transport which is purely diffusive in nature can be modeled using a Brownian force. This model shows how to add such a force in the Particle Tracing for Fluid Flow physics interface. Particle diffusion in a fluid is modeled with the diffusion equation and the Particle Tracing for Fluid ... Mehr lesen
An electron gun must be able to draw a sufficient current and accelerate the electrons to the desired speed. The first part of an electron gun geometry presents unique design challenges because the emitted electron speeds are usually lowest there, and therefore the space charge density ... Mehr lesen
This example considers the natural convection of air above a smoldering incense stick. This kind of flow often shows a transition from laminar to turbulent which is nicely visualized by the smoke produced by the slow burning of the incense. The model uses the Nonisothermal Flow, LES RBVM ... Mehr lesen
This tutorial utilizes the Particle Beam feature to examine the performance of a high-precision spectrometer. An ion beam is subjected to electric and magnetic forces, and only a fraction of the incoming beam is transmitted to the detector. The Particle Counter feature is used to compute ... Mehr lesen
