Book Description
The damping-in-roll parameter C(iota)(p) is calculated theoretically for triangular wings on cylindrical bodies and for a class of wings with sweptback plan forms. The analysis is based on the usual assumptions of linearized compressible-flow theory together with the added restrictions that at the free-stream Mach number M(omicron) the product of lM(omicron)(2) and the streamwise velocity gradient is small.

Generalized Tables of Corrections to Thermodynamic Properties for Nonpolar Gases
Author: Harold William Woolley
Publisher:
ISBN:
Category : Gas
Languages : en
Pages : 670
Book Description
Tables are presented based on the Lennard-Jones 6-12 potential for nonpolar molecules to be used in the representation of second and third virial coefficients and equation-of-state corrections for enthalpy, entropy, specific heats at constant volume and at constant pressure, the ratio of specific heats, the isentropic expansion coefficient, and the velocity of sound. The treatment for effects involving three molecules jointly uses an empirical adjustment of the Lennard-Jones force parameters within a cluster of three independently of the value for an isolated pair. A graphical correlation of ratios of these parameters with the critical constants is also shown which permits better estimates for compact nonpolar molecules with known critical constants but with limited data of state.

Effect of Oxygen Content of Furnace Atmosphere on Adherence of Vitreous Coatings on Iron
Author: A. G. Eubanks
Publisher:
ISBN:
Category : Cobalt oxides
Languages : en
Pages : 672
Book Description
A series of vitreous coatings of the same basic composition, but with cobalt-oxide contents varying from O to 6.4 percent by weight, fired on ingot iron in atmospheres consisting of various oxygen-nitrogen mixtures. The effect of the oxygen content of the atmosphere on adherence was determined by subjecting each specimen to the American Society for Testing Materials adherence test, and the effect of interface roughness was estimated from examination of metallographic sections.

Statistical Study of Transition-point Fluctuations in Supersonic Flow
Author: J. C. Evvard
Publisher:
ISBN:
Category : Aerodynamics, Supersonic
Languages : en
Pages : 692
Book Description
The random movement of the transition point on a 10 degree cone at a free-stream Mach number of 3.12 was investigated by means of a large number high-speed schlieren photographs. The distribution functions which statistically define the transition-point location were determined for a range of test-section Reynolds number and two levels of free-stream turbulence intensity. The intensity was varied by changing tunnel settling-chamber configurations. Temperature-recovery-factor distributions were also obtained.
