An approximate method, an empirical one, a semi theoretical one, and the procedure due to Lindsay and Bromley are examined for prediction of thermal conductivity of polar-nonpolar gas mixtures. With a modification of the approximate method we find, by analyzing experimental and calculated results of twelve different systems, that prediction of thermal conductivity is possible with an uncertainty of about 2%. This is important because experimental data on such gas systems are rare. The methods also permit computation of thermal conductivity at moderately high temperatures and for multicomponent mixtures.read more

Comparison of approaches for measuring the mass accommodation coefficient for the condensation of water and sensitivities to uncertainties in thermophysical properties.
TL;DR: This represents the first effort to assess and compare measurements made by different techniques to attempt to reduce the uncertainty in the value of the mass accommodation coefficient and shows that the measurements are consistent within the uncertainties inherent to the thermophysical and experimental parameters.

The revised URGAP model to describe the gap conductance between fuel and cladding
K. Lassmann,F. Hohlefeld +1 more
TL;DR: The URGAP gap conductance model has been extended and revised generally as mentioned in this paper, and an enlarged data base consisting of approximately 1000 data has been constructed and was used to calibrate the revised UGLAP model.

Chung K. Law,H. K. Law +1 more
TL;DR: In this paper, a theory is developed to account for the variable nature of the specific heats C and the transport coefficients of thermal and mass diffusion, λ and D, in quasi-steady one-dimensional diffusion flames, using bipropellant droplet combustion as an illustration.

TL;DR: In this article, an approximate formula for the thermal conductivity of multicomponent gas mixtures is derived from rigorous kinetic theory by well-defined approximations, and the form of the formula is quite similar to the earlier empirical Lindsay-Bromley equation.
