Thermodynamic properties of air from 1000k to 10,600k along contours of constant density, enthalpy, and entropy(
Book
)
1 edition published in 1961 in English and held by 1 WorldCat member library worldwide
The gas properties given in the report were computed from tables of thermodynamic properties furnished by the National Bureau of Standards. The NBS data have appeared as NBS(1959). It was the purpose of the computation to tabulate properties along isentropes and along constant enthalpy contours, based on the NBS data which are given along isotherms. (Author)

Calculation of supersonic flow around axisymmetric flares(
Book
)
1 edition published in 1958 in English and held by 1 WorldCat member library worldwide
A machine program for the computation of supersonic flow around an axisymmetric flare is described. The computation consists of the following parts: (1) The oblique shock problem in which upstream flow properties vary with position. (2) Calculation of the initial shock angle at the compression corner. (3) Insertion of characteristics for uniformity of mesh size

The stream function equation for a hightemperature gas in axisymmetric rotational flow(
Book
)
1 edition published in 1957 in English and held by 1 WorldCat member library worldwide
A stream function equation for a hightemperature gas in axisymmetric rotational flow has been derived by Garabedian using a constant 'gamma' to relate h, rho and p in one equation and the same constant to relate p, S, and rho in another equation. The present derivation avoids such restrictions on the form of the functional relationships between the thermodynamic variables

A measurement of the electrical conductivity of ionized gases(
Book
)
1 edition published in 1960 in English and held by 1 WorldCat member library worldwide
Two methods were used in attempts to measure the electrical conductivity of various substances, in particular that of a plasma jet. Transients flowing in a system of coupled circuits were subtracted in such a way that the difference signal is due only to the presence of the conducting material. The amplitude and time decay of the signal are calculable fuctions of the conductivity. This method worked well on graphite, but was too insensitive for aqueous salt (NaCl) solutions. Therefore, it cannot easily be applied to the case of an air arc jet exhaust. The steadystate AC measurement technique was tried next. Resonance properties of a coil coupled to the conducting material were measured and compared to the corresponding properties of the same coil in the absence of the conducting substance. This method was used on salt water in the frequency range of 110 mc. It was found to be sufficiently sensitive that the accuracy of the conductivity measurement was expected to be about 10%. Two problems were encountered, however, that were not solved

Thermodynamic properties of air from 9500k to 14,800k along contours of constant density, enthalpy, and entropy(
Book
)
1 edition published in 1961 in English and held by 1 WorldCat member library worldwide
The tables represent an addendum to AD607 607. In the computations for the 'Addendum' an attempt was made to provide sufficient overlap that the derivatives and the speed of sound values near the junction between the tables are the same as they would have been if the entire computations had been carried out in one pass on the machine.
