Book excerpt: The report presents the results of experimental and analytical investigations of the confined coaxial mixing of isoenergetic air streams. Both uniflowing and counterflowing secondary air streams are considered. Laminar and turbulent uniflow mixing are treated analytically. The results of experimental investigations of turbulent mixing are used to calculate the radial as well as the axial variations of eddy viscosity and the turbulent diffusion coefficient up to 25 jet diameters downstream of jet orifice. New expressions are developed to yield reliable values in regions of mixing where existing expressions become indeterminate. Special consideration is given to the case where the two streams have equal velocity. The experimental investigation of turbulent counterflow mixing shows that a toroidal shaped vortex is set up at the jet interface which gives rise to depressed static pressures. Over the range of parameters investigated, entrainment of fluid from the inner jet into the external stream takes place downstream of the vortex. (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.

Available in PDF, EPUB and Kindle. Book excerpt: A program of experimental and analytical research to study coaxial jet mixing was initiated. Test apparatus was designed, and a test plan was developed. The apparatus provides for an axisymmetric primary stream which simulates the exhaust of a fuel-rich rocket motor and a coaxial secondary stream of air. Both streams are contained by a constant area duct. Wide variations of composition, temperature and velocity can be systematically imposed on the primary stream, and the temperature and velocity of the secondary stream can be varied. A broad permutation of flow and composition parameters involving the primary and secondary streams has been planned. The results of the reanalysis of early single particle boron combustion data were analyzed in terms of a more sophisticated model of the combustion process. Three phases of boron combustion are identified: (1) a heatup phase marked by convective heat flux into the particle; (2) an ignition phase in which surface reactions as well as convection control particle temperature; and (3) a combustion phase where particle temperature has reached the boiling point of its oxide. Estimates of both heatup time and ignition time are in good agreement with experimental data. Preliminary results of an analysis to determine the effect of particles on the mixing of compressible streams are given in terms of jet spreading parameters for the primary and secondary streams and the particle boundary in the mixing zone.
