Available in PDF, EPUB and Kindle. Book excerpt: A few simplified flow situations from submerged outlets have been studied experimentally as an initial step towards understanding the mechanics of submerged flow from outlets. These are, the water wall jet, the reattached wall jet due to submerged flow from outlets situated over a drop, and the flow from outlets situated on the bed at a sudden symmetrical expansion in the width of a channel. The classical wall jet has been chosen as the basic flow model. In each of these problems the velocity profiles have been analysed for similarity and when similarity exists the variation of the, length and velocity scales have been studied. The bed shear stress variation data have been obtained and correlated with the flow parameters. Some information on the boundary layer characteristics has also been obtained. In connection with the study of the flow from finite size outlets on the bed at sudden width expansions, a characteristic length of the outlet has been defined and is found to be very useful in correlating the various data. This length parameter is found to be useful in correlating the available data for the maximum velocity decay of three-dimensional free jets also (Appendix B). The gross characteristics of two types of hydraulic jumps occurring at a sudden symmetrical expansion in a channel have also been studied in detail and interesting results have been obtained. The velocity and pressure field immediately below a deeply submerged sluice gate have been studied in Appendix A. A vena contracta for the submerged flow has been defined and studied. The profile of the hydraulic jump in a rectangular channel has been analysed for similarity and a single non-dimensional similarity profile, with simple scales, has been obtained, in Appendix C.

This book was released on 1971 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental study of various wall jet flows was conducted. The major areas of investigation were: The wall jet injected into still air; The wall jet under a constant-pressure main-stream flow; The wall jet subjected to an adverse pressure gradient imposed by a retarded main-stream flow with a substantially thickened initial boundary layer; The wall jet subjected to an adverse pressure gradient imposed by a retarded main-stream flow with a thickened and distorted initial boundary layer. Detailed velocity profile and local skin friction measurements were made at numerous streamwise distances from the jet slot. For the case in which no main-stream flow was present, the studies were carried out for a wide range of slot Reynolds numbers. For the wall jets with main-stream flow, selected ratios of free-stream velocity to jet velocity at the jet slot were investigated. The growth of characteristic thickness and decay of jet peak velocity is presented for all wall jet studies. Also, velocity and temperature profile similarity is described. Skin friction laws are shown for the constant-pressure wall jets and a single 'law of the wall' valid for all wall jet studies is set forth. Finally, the skin friction and velocity profile measurements are presented in tabular form. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The industrial effluents and municipal wastewater plant effluents discharged into a stream are expected to undergo dilution in a short reach of the stream. To permit this, the devices used to discharge the effluent should ensure rapid mixing of the effluent in the stream. Jets act as simple and efficient devices that accomplish this task. Counter flowing wall jets located in closed conduits can also be used for efficient mixing of chemicals used in water and wastewater plants. The increased interest in the use of cross jets and counter flowing jets to ensure proper mixing of effluents in a stream can be traced to the larger scales of mixing achieved by these devices, as compared to the traditional co-flowing jet devices. Existing counter flowing wall jet studies are mostly limited to the determination of the mean flow characteristics of the jet. These include the determination of the functional relationship among the main jet parameters such as the jet velocity ratio, the width of the recirculation zone and the penetration length of the jet. In the present study, the mean and turbulent mixing characteristics of the counter flowing wall jets were determined experimentally using a Laser Doppler velocity meter (LDA). This information was used to find the dependence of the length scales and the velocity scales of the counter flowing wall jet on the basic parameters. To validate the experimental procedure, the mean velocity profiles, turbulent components and jet expansion angle of wall jets were determined. The validation was quite good.
