Book excerpt: Turbulent coaxial air-air mixing and hydrogen-air mixing were studied. The ratio of outer stream to jet veolcity was varied from 0.12 to 1.52 for the air-air mixing systems and from 0.16 to 0.42 for the hydrogen-air systems. Special emphasis was placed on the determination of the turbulent transport properties (especially the eddy viscosity and the Prandtl number) from the mean flow field measurements by use of an integral technique. Radial and axial profiles of velocity, concentration, shear stress, and eddy viscosity are presented, as well as radial profiles of the turbulent Prandtl number and representative static pressure profiles. In addition to the graphical presentation of the data, the mean flow field properties are presented in tabular form. The major conclusions of this investigation are: (1) the experimental technique used produced good quality meanflow field data; (2) the integral technique used for calculating the turbulent transport properties from the mean flow field data gave satisfactory results; (3) for the air-air system, a significant radial variation of the second regime eddy viscosity was observed for most of the tests; (4) the eddy viscosity decreases with increasing radius for the hydrogen-air systems; and (5) approximate average values for the turbulent Prandtl number are: 0.60 for the air-air tests and 0.80 to 0.85 for the hydrogen-air system.

This book was released on 1965 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental study is presented of the turbulent mixing of two coaxial air jets at subsonic-supersonic speeds in a closed duct. The investigation was undertaken to obtain velocity profiles and axial velocity decay results and other turbulent flow properties with existing PIBAL equipment, and to analyze the conditions needed for an improved experiment. By using a suitable total pressure it was possible to correctly expand the ducted outer jet to ambient conditions. Negligible pressure gradients were found in a considerable region of the duct and all static and stagnation pressure measurements were made in the regime. The axial velocity decay was thus determined. On the basis of the pressure measurements the flow field was divided into three mixing regions. In each of these regions the normalized velocity and total pressure profiles were correlated with values of the axial and radial coordinates. Jet boundaries were measured and an eddy viscosity function calculated. Detailed recommendations are made for improvements of this type of experiment. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Proceedings of the XXth International Astronautical Congress compiles selected papers presented at the 20th International Astronautical Congress held in Mar del Plata, Argentina in 1969. This book is divided into five main topics—spacecraft engineering, astrodynamics, astrionics, bioastronautics, and problems of education. In these topics, this compilation specifically discusses the equatorial vibrations of a long flexible boom on a spin-stabilized satellite of non-zero radius; heat transfer to linear bodies in two-dimensional hypersonic low density; and limits of accuracy of general perturbations for satellites moving under constant forces. The rapid optimization of multiple-burn rocket flights; data transmission for planetary studies; and comparison of theoretical and experimental attitude data for the DODGE spacecraft are also elaborated. This text also covers the Apollo life-support and protective systems; bioastronautical aspects of Apollo biomedical operations; and development and applications of hot water rockets. This publication is recommended for astrophysicists and scientists of other disciplines related to astronomy.
