The VizSpark software is used to perform a 2-D simulation of a model spark plug channel with cross-flow. Coupling between arc physics and conjugate heat transfer to the electrode was performed. The ability to predict spark restrike events was also demonstrated. Furthermore, an estimate of electrode ablation is also made. The spark plug has been a reliable source of ignition for well over 100 years.  The ignition source plays a pivotal role in the efficiency

This application overview discusses the modeling of a flow-through Inductively Coupled Plasma (ICP) reactor with VizGlow and provides an example of tightly coupled multi-physics simulations with the software.  Discharge physics including multi-temperature, multi-species transport, and finite-rate plasma chemistry effects are coupled to electromagnetic wave phenomena driven by inductive coils, and a bulk fluid flow through an inlet/outlet configuration.

The geometry and mesh for the plasma discharge simulation are shown in Figure 1.  The axisymmetric discharge

3D Microwave Plasma MWP Simulation in VizGlow

This example application simulates a steady microwave field in a three-dimensional plasma reactor using in semiconductor materials processing.  The Frequency-Domain Electromagnetic Wave Solver Module of the VizEM is used for this problem. The geometry for the simulation is shown in Figure 1 and comprises a cylindrical processing reactor with an air-filled waveguide port in the top center of the reactor.  The waveguide is rectangular in cross section and comprises an L-bend with a 45o mirror surface

Capacitively Coupled Plasma (CCP) discharges in parallel-plate configuration are commonly used in semiconductor and other materials processing applications.  These discharges provide a compact platform in which a plasma can be generated to process a flat wafer surface.  The highly directional ion impact at the wafer surface with high ion impact energies is beneficial to a number of wafer processes; in particular for etch processes.  This application note discusses the simulation of a typical CCP reactor

Esgee Technologies Inc. presents “Simulations of Spark-Plug Transient Plasma Breakdown in Automotive Internal Combustion Engines” at SAE World Congress on April 6th, 2017. This work investigates the dynamics of spark breakdown and quantifies its effect on electrode damage for different electrode geometries. Ion bombardment and sputtering on the cathode surface are quantified. Quantifying this behavior is critical to understanding (and ultimately improving) spark plug reliability and electrode lifetime.
