High-Temperature Transport Properties of Dissociating Hydrogen

Abstract: The transport properties of dissociating hydrogen gas have been calculated from 1000°K to 15 000°K with the assumption of no ionization or electronic excitation. The rigorous kinetic-theory formulas, which have recently been modified to take into consideration the multiplicity of interaction curves, were used in the calculations. The transport coefficients at each temperature are tabulated as a function of composition rather than pressure for reasons of compactness and ease of interpolation. The fact that the … Show more

“…In this connection we note that the use of 0(") , derived from the experimental charge transfer cross-sections of [9] affect À-Tot and q by not more than 15 % as compared with the present results based on the charge transfer cross-sections of [3] (see Fig. 1-2 [15], which have been found to be in good agreement with recent experiments [16]. Figure 5 shows a comparison of the total thermal conductivity of an atmospheric hydrogen plasma with the experimental values recently derived by Popovic and Konjevic [4], correcting the radial temperature distribution of [17].…”

“…Thus the internal energy is not negligible compared with the translational energy, and this first-order approximation must be used with considerable reservation in this case. Nevertheless, this is the approximation that is almost always used in estimating the effects of inelastic collisions on transport properties [Vanderslice et al, 1962 In this approximation, the viscosity is given by [Mason and Monchick, 1962] (MT) •/2 rt = 2.669 X 10 -6 a2f•2,2), kg/m/s…”

“…and the internal contribution to the thermal conductivity, λ int , is given by [6,7] λ int (W · m −1 · K −1 ) = 1.203 × 10 4 pD T (C p − 20.786) (4) where T is the temperature in K, M is the molar mass in g· mol −1 , p is the pressure in bar, C p is the molar heat capacity at constant pressure in J· mol −1 · K −1 , and σ 2 (1,1) * , and σ 2 (2,2) * are the diffusion and viscosity collision integrals in 10 −20 Å 2 , respectively, determined by the interaction between two Ag atoms as they "follow" a particular electronic potential energy curve. Equation (4) is valid subject to the assumption that the transport of internal energy is due only to a diffusion mechanism [6,7].…”
