This tutorial model presents a study of a coaxial DC corona discharge in dry air at atmospheric pressure. The dimensions and operation conditions are similar to ones found in electrostatic precipitators with wire-to-plate configurations. The inner wire electrode has a 100-mm radius and ... 詳細を見る
This tutorial model shows how to set up a model of a pulsed capacitive discharge. The on pulse consists of 10 periods of excitation at 13.56MHz, followed by no excitation for 100 periods. The I-V characteristics, the electron density, temperature and plasma potential are studied. 詳細を見る
This tutorial model presents a study of a double-headed streamer in nitrogen at atmospheric pressure. An initial seed of electrons is placed between two electrodes which apply an initial electric field of 52 kV/cm to the gas. A negative and positive streamer propagate toward the ... 詳細を見る
This model shows how shape optimization can be used design the coils of an ICP reactor to obtain plasma uniformity. The reactor in study is a planar ICP with the coils distributed along the radial direction. The Optimization study step is used to find the best coil placement so that the ... 詳細を見る
Surface chemistry is often an overlooked aspect of reacting flow modeling. This tutorial model shows how surface reactions and species can be added to study processes like chemical vapor deposition (CVD). The tutorial then models silicon growth on a wafer. Initially, the example uses a ... 詳細を見る
This tutorial model demonstrates how to compute the impedance of a capacitively coupled plasma. The Time Periodic study computes the time periodic solution of the plasma. Subsequently, the solution is transformed to the time domain, after which the fast Fourier transform (FFT) solver is ... 詳細を見る
In this example, a hydrogen plasma reactor at moderate pressure is studied using a global model. The heavy species heat equation is included. In the first part of the study, a Maxwellian electron energy distribution function is used. In the second part, the global model is solved self ... 詳細を見る
This model solves the Boltzmann equation in the two-term approximation for a background of molecular and atomic hydrogen. Electron mobility and source terms are computed by suitable integration of the electron energy distribution function over electron impact cross sections. 詳細を見る
This tutorial drives a capacitively coupled plasma with an L-type matching network at high and low powers. At low power, where the harmonics in the current are low, prefect matching is obtained at the chosen power value. Sweeps over power, frequency, and pressure are performed and their ... 詳細を見る
The underlying physics of a capacitively coupled plasma is rather complicated, even for rather simple geometric configurations and plasma chemistries. This model benchmarks the Capacitively Coupled Plasma physics interface against many different codes. 詳細を見る
