Zero dimensional, time-dependent plasma chemistry and chemical kinetics code.
Features
- Full time-dependent plasma chemistry (no limit on number of atomic and molecular species)
- Reactions read in symbolic for and rate coefficients in Arrhenius form (no limit on number of reactions)
- Handles neutral, ionic & electron collisional, radiation and diffusion processes
- Line broadening and escape factor model for line radiation; continuum radiation model
- Uses ELENDIF for computing transport and rate coefficients for non-Maxwellian electrons
- Can use tabulated Maxwellian rate coefficients vs. Te, which it can generate internally from tabulated cross section data
- Can perform calculations at constant current density, constant power density, or with a voltage source + ballast resistor circuit
- Can treat heating of electrons by inverse bremsstrahlung
- Can treat a time dependent external source of electrons, such as an electron beam
- User friendly interface with pull-down menus and help screen
- Graphical output with printer and graphics file support
Example Calculation 1: Constant Current Discharge in an N2H2 Gas Mixture
- Log-log plot of electron and ion densities
- Semi-log plot
- Electron energy distribution functions parametric in E/N
Example Calculation 2: Pulsed Discharge in He/Ar/O2 Gas Mixture With Voltage Source and Ballast Resistance
Example Calculation 3: Pulsed Discharge in Humid Air
- Electrons and oxygen negative ions
- Positive ions
- O, O3, and metastable states
- NOx
- Electron distribution function at various times (the peaks are due to superelastic collisions with metastable species)
- Air chemistry model
