Available in PDF, EPUB and Kindle. Book excerpt: The report describes the results of an experimental study concerning the injection of a gaseous secondary jet into an unbounded supersonic flow field which was uniform outside of a turbulent boundary layer. The investigation was principally concerned with the definition of the proper scale length to be associated with turbulent two-dimensional jet-interaction flows. In support of this objective, results are presented for a Mach 4 test conducted using a flat-plate model containing a sonic secondary jet directed normal to the mainstream. Secondary jet strengths were varied from approximately 0 to 1000 for jet throat sizes of 0.005 inch, 0.020 inch and 0.030 inch. The jet interaction phenomenon was studied using detailed surface pressure distributions measured fore and aft of the secondary jet in conjunction with comprehensive shadowgraph coverage of the interaction flow field.

Available in PDF, EPUB and Kindle. Book excerpt: The report describes the results of an experimental study involving a two-dimensional, underexpanded, free jet flowing into a static medium. The investigation was concerned with the determination of jet heights as a function of the nozzle flow properties. In support of this objective experimental results of two supersonic nozzles (Mach numbers of 2.89 and 2.99 and throat widths of 0.0335 inch and 0.0204 inch, respectively) are presented along with a complete data tabulation which includes photographs. A universal data correlation, expanded to include the axisymmetric jet case, is presented.

Download or read book Correlation Parameters for Two dimensional Jet Interaction written by Richard E. Lottero and published by . This book was released on 1973 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem considered is the separation of the boundary layer on a flat plate in a high supersonic free stream caused by the normal injection of a two-dimensional sonic or supersonic jet. Only the separation region forward of the jet is discussed. Data from existing literature has been analyzed to form dimensionless correlation parameters that will accurately predict the force, center-of-pressure, and separation length that characterize this forward separation region. Problems related to the nozzle discharge coefficient are discussed. The functional relations of these correlations with respect to changes in jet stagnation temperature and pressure, nozzle throat width, and Mach number for fixed free stream conditions are also discussed.

Book excerpt: An experimental investigation involving a thick, adiabatic, naturally turbulent, two-dimensional boundary layer undergoing separation has been completed at the Naval Ordnance Laboratory (NOL). Forward facing steps (with attached end plates) were used to induce boundary-layer separation for the particular case where the step heights, h, were less than the boundary-layer thickness, delta. The tests were conducted at a free-stream Mach number of 4.9 with a range of unit Reynolds numbers varying from 0.8 x 10 to the 6th power per foot to 4.0 x 10 to the 6th power per foot. The pressure distributions measured in the separated region ahead of the steps were found to be functions of both Re sub delta and h/delta for the turbulent boundary-layer separation case where h

This book was released on 1968 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem discussed is that of theoretically predicting the normal force induced in the boundary layer separation region immediately ahead of a secondary injection port. Attention was limited to the two-dimensional problem of sonic or supersonic normal injection into supersonic or hypersonic mainstreams. A critical review of available experimental studies was conducted in order to isolate those data best representing a two-dimensional state. The resulting compilation of experimental results was thereafter employed as a basis of comparison for available theoretical and empirical flow models. As a result it was found that analytical means are only capable of rough quantitative estimates of control jet effectiveness and that a more detailed flow model is needed to further explain observed phenomenon. The basic features of such a model are formulated and its conceptual validity demonstrated through comparison with experimental results. Problem areas requiring further research are also discussed in detail. (Author).
