A chemical non-equilibrium model of anairsupersonic ICP

Abstract: A numerical model for an air inductively coupled plasma (ICP) torch with a supersonic nozzle is developed using reaction rates under chemical non-equilibrium. The reaction model takes into account 11 species (neutral species: N2, O2, NO, O, N and charged species: , , NO+, O+, N+, e−) in air ICP. The species distribution in the air inductively coupled thermal plasma with a supersonic nozzle is obtained by solving the mass conservation equations taking into account diffusion, convection and chemical reactions.… Show more

“…Properties of air plasmas have been of interest to people over many decades [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. Initially, it was primarily due to their relations to space programs and the highest temperature of interest was fairly low (\ 20,000 K).…”

“…It assumes that the electron temperature is in equilibrium with the heavy particle temperature. A non-LTE approach can be divided into two parts: the chemical non-equilibrium which is due to finite kinetic rates [19][20][21] and the thermal non-equilibrium addressed specifically at the electron temperature not in equilibrium with the heavy particle temperature [22][23][24][25][26][27]. Both approaches are obviously concerned with some limitation in the collisional processes that would not be sufficient to sustain equilibrium.…”
