Available in PDF, EPUB and Kindle. Book excerpt: This report includes: EFFECTS OF INTERMOLECULAR INTERACTIONS ON THERMODYNAMIC PROPERTIES OF GASES AT HIGH TEMPERATURES AND PRESSURES, by Harold W. Woolley. 1962, 22p. incl. illus. The calculation of thermodynamic properties of gases at high temperature using ion solution theory is analyzed in regard to various details. Earlier work based on rigid sphere ions is enlarged on briefly. An extension to a more general case of realistic pair interactions is also obtained. With Debye screened ionic interactions, a study is made of effects of repulsions and both continuum and bound states for ionic attractions; simple approximate representations of the interaction effects for the two free particle interaction cases are given. For the bound states, the finite number of states available for occupancy as a result of Debye screening is explicitly indicated, and a numerical method to adjust from an arbitrary state sum to the ''Debye screened'' sum is explained. An extensive compensation between bound states just below the continuum and a partial state paucity within the continuum are also noted. Other details considered include the estimation of the dielectric constant up into the region of high density and high temperature, the semi-empirical estimation of nonbonding pair interactions involving neutral and ionized species, and corresponding virial-type exclusion effects. A table of second virials for constituents of air up to 20,000 K is included. (Author).

This book was released on 1963 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Viscosities and thermal conductivities, suitable for heat-transfer calculations, were estimated for about 200 gases in the ground state from 100° to 5000° K and 1-atm pressure. Free radicals were included, but excited states and ions were not. Calculations for the transport coefficients were based upon the Lennard-Jones (12-6) potential for all gases. Intermolecular force constants for this potential were obtained from experimental viscosity data or were estimated when data were not available. The same set of constants was used to calculate both viscosity and conductivity. An Eucken-type correction for exchange between internal and translational energies was made for thermal conductivities of polyatomic gases.

This book was released on 1968 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: The partition function corresponding to an equation of state for a high-temperature, high-density gas suggested by J.S. Rowlinson was derived. The equations for selected thermodynamic properties of the gas are obtained from this partition function using statistical thermodynamics. These equations are used to calculate results for the case of hydrogen in the range of temperature between 500K and 3000K and in the range of density between 1 and 2000 amagats.

Download or read book Approximations for the Thermodynamic and Transport Properties of High temperature Air written by C. Frederick Hansen and published by . This book was released on 1959 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thermodynamic and transport properties of high-temperature air are found in closed form starting from approximate partition functions for the major components in air and neglecting all minor components. The compressibility, enthalpy, entropy, the specific heats, the speed of sound, the coefficients of viscosity and of thermal conductivitiy, and the Prandtl numbers for air are tabulated from 500° to 15,000° K over a range of pressure from 0.0001 to 100 atmospheres. The energy of air and the mol fractions of the major components of air can be found from the tabulated values for compressibility and enthalpy. It is predicted that the Prandtl number for fully ionized air, which is in complete equilibrium, will become small compared to unity, the order of 0.01, and this implies that boundary layers in such flow will be very transparent to heat flux.

This book was released on 1966 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research performed under this contract was directed primarily into two areas. In the first, an analysis of the problems of calculating the thermodynamic properties of a high temperature gas was undertaken in an effort to find reliable methods of extending present data to much higher temperatures. Accurate thermodynamic data are especially required for the high temperature region, perhaps to temperatures reaching 6000 Kelvin for systems deriving their energy from chemical reactions and to substantially higher temperatures for plasma systems. In the second area, an analysis was undertaken of problems associated with the prediction of transport properties in high temperature gas mixtures, especially systems with some degree of ionization or molecular excitation. A precise knowledge of the various interaction potentials between the reacting species is essential for a complete understanding of the high temperature behavior of such systems and for calculating the transport properties.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this report is to survey critically the efforts made in the past years to gain an understanding of the high-temperature thermodynamic properties of air species and to describe the basic methods used for their calculation. The report also contains the theoretical background and the required input data upon which a new calculation of the thermodynamic properties for high-temperature air species has been carried out in the temperature range 50 to 100 000 K. The results obtained from this new calculation are presented in the form of tables in an associated report (ESA STR-237).
