Thermodynamic and Electrical Properties of Combustion Gas and Its Plasma : 1st Report, Theoretical Calculation

Abstract

Fourteen thermodynamic and electrical properties, including isentropic exponent, viscosity and thermal conductivity, of combustion gas and its plasma, which contain C, H, O, N, S and K, as elements, are calculated by IBM 7090, assuming the system is in equilibrium. Petroleum (C_nH_2n) and coke (C) combustion gases and their plasmas are treated. The conditions of calculation are : temperature ; 0∼4000°K, pressure ; 0.2∼8.0 atm, equivalence ratio ; 0.8∼1.5, N₂/O₂ ratio ; 0∼79/21 (air) and K₂SO₄ seeded ratio ; K/C=0.02∼0.4. K₂SO₄, K₂CO₃, K₂O, KO are considered in addition to KOH, K and K⁺ which have been treated in the previous papers as the potassium compounds caused by the dissociation of the seeded potassium salt. The results are compared with those of only KOH, K and K⁺ being considered.
