This book was released on 2012 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the numerical and experimental study of oscillations in laminar free and impinging jets. A finite volume algorithm based on non-orthogonal cells has been used to solve the transient, incompressible Navier-Stokes equations for two dimensional flow. The code has been employed for the prediction of flow and thermal oscillations in isothermal and non-isothermal jets. For free jets, the effects of parameters such as Reynolds number, inlet temperature and jet orientation on oscillations have been studied. For impinging jet flow, the effects of stand-off distance, Reynolds number and inlet temperature on mean flow as well as jet oscillations have been studied.

Available in PDF, EPUB and Kindle. Book excerpt: Some experimental and theoretical studies have been made of axisymmetric free jets exhausting from sonic and supersonic nozzles into still air and into supersonic streams with a view toward problems associated with propulsive jets and the investigation of these problems. For jets exhausting into still air, consideration is given to the effects of jet Mach number, nozzle divergence angle, and jet static-pressure ratio upon jet structure, jet wavelength, and the shape and curvature of the jet boundary. Studies of the effects of the ratio of specific heats of the jets are included as are observations pertaining to jet noise and jet simulation. For jets exhausting into supersonic streams, an attempt has been made to present primarily theoretical curves of the type that may be useful in evaluating certain jet interference effects and in formulating experimental studies. The primary variables considered are jet Mach number, free-stream Mach number, jet static-pressure ratio, ratio of specific heats of the jet, nozzle exit angle, and boattail angle. The simulation problem and the case of a hypothetical hypersonic vehicle are examined. A few experimental observations are included.

This book was released on 1971 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation was conducted to determine dynamic characteristics of a circular, fully developed, laminar free jet. Complete velocity profiles are presented at Reynolds numbers of 437 and 1839 at 0, 3, 6, 10, 15, and 25 diameters from the nozzle exit. Centerline velocity decay was obtained over a range of Reynolds numbers from 255 to 1839. Also presented are the angles of spread associated with the diffusion of the jet downstream of the nozzle. Where possible, results are compared with those obtained for laminar jets having an initially flat or uniform velocity profile at the nozzle exit.

This book was released on 1979 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental study of the flow field associated with a two-dimensional, supersonic jet impinging normally on a flat plate is reported. Two wedge nozzles manufactured at the design Mach numbers of 1.75 and 2.75, respectively, were used to provide the jet. Extensive pitot surveys of the free jet were first conducted to determine the quality of the free jet. Results indicate that the simple wedge nozzles were adequate in providing the desired two-dimensional jet in the free expansion configuration. Results of surface pressure measurements and schlieren photographs of the impingement flow indicating the shock patterns are then presented and discussed. Although the results are principally reported for the case of the jet at isentropic exit conditions, some results of underexpanded and overexpanded jets are also included. Some discrepancies between the experiment and the simple theory based in the method of integral relations and the inviscid flow model are noted and discussed. An 'effective' jet Mach number is introduced which accounts largely for the discrepancy between experiments and theory, and its determination is based on the measured stagnation point pressure on the plate surface.

Download or read book An Experimental Study of Jet Impingement on a Circular Cylinder written by Dennis Wayne Potts and published by . This book was released on 1984 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: A round turbulent jet was impinged normally upon a circular cylinder and the resulting flow field was studied. The investigation was conducted using a jet which issued from a nozzle with an 11/16 inch diameter. The cylinder had a diameter of 6 5/8 inches. The jet impinged upon the cylinder at nozzle distances of 7, 15, and 30 nozzle diameters, and at velocities of 400 and 500 ft/s. The free jet was studied and found to be 'typical' by comparing it to earlier studies done with round turbulent jets. Surface flow visualization tests were performed to determine the direction of the flow. The wall jet about the cylinder, resulting from the impinging jet, was studied. Measurements of the velocity profiles and turbulence intensities were made. These results were compared to the same information obtained for flat plates and found to be similar for the nozzle distance of 7 diameters. At nozzle distances of 15 and 30 diameters the data was no longer similar. From velocity measurements, the spread rates and decay rates of the wall jet were determined. These results were compared to similar studies done for flat plates. Decay rates were found to be less than that of flat plates and spread rates were greater than that of flat plates, especially about the circumference of the cylinder.

This book was released on 1966 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of an experimental study of the heat transfer below normally impinging jets are presented. These results are correlated on the basis of the local mean flow and turbulent characteristics of the free jet that would exist in the plane of impingement were this plane to be removed. In order to make these local correlations possible, a rather extensive survey of the turbulent characteristics of the free jet used in the experiments is made that can be used in connection with previous studies of the local mean character of the jet. On the basis of the method of local correlations which is developed, a rationale for computing heat transfer distributions below impinging jets is suggested. (Author).
