【Abstract】 The method and results of calculating chemical composition in equilibrium, themody-namic and electrical physical properties of seeded combustion gas plasma are described. Effects of these properties on some performances of MHD power generators are treated. In this calculation 23 components and 20 thermodynamic and electrical properties are considered.The conditions of calculation are:fuel: Diesel oilO2/N2+O2:φ= 0.2315 (air) to 1.0 (pure oxygen)equivalence radio: αΣ=0.7 to 1.1potassium content: ε= 0.01 to 0.03concentration of K2CO3 in aqueous solution: m = 0.5 to 1.0temperature of oxidizer: Tp= 298 K to 2000 Ktemperature of the combustion products: T = 2000 K to 3400 Kmagnetic induction: B = 2 or 5 wb/m2The data have been used for designs, theoretical analyses and diagnoses of MHD power generators.更多还原
