Book Description
An experimental investigation of the turbulent mixing of a sonic jet of helium discharging coaxially into a supersonic jet of air was made using a two dimensional mixing chamber. Volumetric concentration profiles were obtained and mass concentration and velocity along the jet centerline were plotted. The results indicated that both these vary inversely with the distance from the mixing origin raised to a four third power. Schlieren photography was applied in a semi-quantitative manner to confirm the validity of the above findings. This research project finds a potential application in the study and analysis of supersonic combustion ramjet engines. (Author).

Book Description
An experimental investigation of the turbulent mixing of subsonic, sonic, and supersonic jets of helium discharging transversely into a supersonic jet of air was made using a two-dimensional mixing chamber. The investigation has a potential application in the field of the supersonic combustion ramjet engine. The Mach numbers of the helium jets were 0.75, 1.0, and 1.5, respectively, and the Mach number of the air jet was 1.5. Both the helium and air jets had stagnation temperatures of approximately 76F. The effects of combustion on the mixing were not considered. Volumetric concentration values and total pressure values were obtained at points in the mixing region, and helium volumetric concentration profiles were plotted. Schlieren photography was used to obtain a visualization of the flow structure. Sonic injection was found to be the most desirable method of injection due to depth of penetration and total pressure considerations. (Author).

Jet in Supersonic Crossflow
Author: Mingbo SunPublisher: Springer
ISBN: 9811360251
Category : Technology & Engineering
Languages : en
Pages : 284
Book Description
Based on research into jets in supersonic crossflow carried out by the authors’ team over the past 15 years, this book summarizes and presents many cutting-edge findings and analyses on this subject. It tackles the complicated mixing process of gas jets and atomization process of liquid jets in supersonic crossflow, and studies their physical mechanisms. Advanced experimental and numerical techniques are applied to further readers’ understanding of atomization, mixing, and combustion of fuel jets in supersonic crossflow, which can promote superior fuel injection design in scramjet engines. The book offers a valuable reference guide for all researchers and engineers working on the design of scramjet engines, and will also benefit graduate students majoring in aeronautical and aerospace engineering.
