Book excerpt: Experimental results on the turbulent mixing process between carbon dioxide and hydrogen central jets exhausting into a moving concentric stream of air are presented. The diffusion of mass and momentum only are considered, since both streams are at approximately equal temperature. The flow velocities are in the low to high subsonic range. Principal points of investigation are the condition of equal velocity between jets and the condition of equal mass flow per unit area between jets. Radial and axial distributions of concentration and velocity are presented. On the basis of the measurements it is concluded that no tendency towards segregation of the stream exists when either the velocities or the mass flows of the streams are equal. Furthermore, it is demonstrated that the product of local density and eddy kinematic viscosity coefficient can be assumed to be solely dependent upon the axial coordinate. In agreement with previous results it is found that mass diffuses more readily than momentum. Finally, a formulation of the eddy viscosity and eddy diffusivity coefficients that adequately describe the results obtained is derived. (Author).

This book was released on 1977 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation of ducted, two stream, subsonic, reactive, turbulent jet mixing with recirculation was conducted. A primary jet of air at a mass flow rate of 0.075 lb/sec and velocity of 700 ft/sec was surrounded by an outer, low velocity, hydrogen stream. Data were obtained with hydrogen-air ratios of 0.143 and 0.107. The duct-to-inner nozzle diameter ratio was ten. Radial distributions of hydrogen mass fraction, mean axial velocity, turbulence intensity, and total pressure as well as axial distributions of wall hydrogen mass fraction and wall static pressure are presented for axial stations from one-half to five duct diameters from the nozzle exit plane. Comparison of the experimental data with calculations assuming frozen or equilibrium chemistry indicate that he measured velocity, pressure, and composition data are, in general, self-consistent. The maximum turbulent intensities which occurred in the center of the mixing layer and within the recirculation eddy were very high having values of 20 percent of the jet exit velocity. The velocity and composition field indicate that, while and mixing in the reactive flow field is slower than for the nonreactive case, the reaction had little effect on the size and location of the recirculation zone within the mixing duct.

Book excerpt: This report covers the work on gas-particle flow performed during the 1973-1974 contract period. Some previous work, which was published during this period, is briefly reviewed. The main effort was directed toward a study of gas-particle jets injected into a cross flow of clean gas. Photographs of the jets were obtained, and penetration of the jet centerline was correlated with the ratio of the momentum flux of the jet to that of the cross stream, and the distance from the injection point. The loading ratio (particle flow rate/gas flow rate) was 25 for these experiments. Results for lower loading ratios were obtained by a parallel study under different sponsorship. The results and their relationship to the few data available in the literature are discussed. A brief assessment is made for the mean free path for particle-particle collisions in two intersecting gas-particle jets. An extensive review of gas-particle flow was prepared with partial support by this contract, and plans for a future experimental study of a recirculating flow are outlined.

Available in PDF, EPUB and Kindle. Book excerpt: An experimental and theoretical investigation of bounded turbulent mixing with chemical reactions is described. Configurations which are applicable to the air-augmented rocket are considered. Experimental results are presented for a mixing apparatus in which a fuel-rich O2-H2 rocket stream was mixed with a secondary airstream inside a conical duct. An integral mixing theory is described, in which conservation equations are satisfied across the duct. The inviscid portions of the duct flow are considered onedimensional, and the mixing zone profiles are assumed to exhibit shape similarity. The theory is extended to include the downstream regime where the mixing region extends across the entire duct. Correlations of the theory with incompressible and reactive compressible mixing experiments indicate that the theory provides a satisfactory over-all representation of the bounded mixing process.
