Available in PDF, EPUB and Kindle. Book excerpt: Applied Mathematics and Mechanics, Volume 2: Jets, Wakes, and Cavities provides a systematic discussion of jets, wakes, and cavities. This book focuses on the general aspects of ideal fluid theory and examines the engineering applications of fluid dynamics. Organized into 15 chapters, this volume starts with an overview of the different types of jets and explores the atomization of jets in carburetors in connection with gasoline engine design. This text then emphasizes the formal treatment of special flows and examines the flows that are bounded by flat plates and free streamlines. Other chapters consider the flows that are bounded by the cavity behind a symmetric wedge. This book discusses as well the intuitive momentum and similarity considerations. The final chapter deals with several surprising physical complications. Mathematician, physicists, engineers, and readers interested in the fields of applied mathematics, experimental physics, hydraulics, and aeronautics will find this book extremely useful.

Available in PDF, EPUB and Kindle. Book excerpt: Assuming the jet mixes turbulently with the surrounding atmosphere, the stagnation pressure corresponding to the centerline conditions of the jet at a point of the cavity's maximum depth, i.e., height of mozzle above liquid plus cavity depth, was equated with the hydrostatic pressure at the cavity's bottom allowing a determination of the depth. The diameter of the cavity or maximum width was predicted for axisymmetric and two-dimensional jets. Prediction of minimum jet pressure required to induce liquid spray was made by an equilibration of surface tension, gravity, and drag forces. Experimental tests of air impinging on both water and wet cement were performed and analyzed along with the results of air impingement on various other liquids. The experimental cavities formed on the water were extremely irregular, however, time exposure photographs allowed detailed inspection of the steady state shape of these cavities. Cavities were also formed on wet cement and by allowing the cement to set with the air jet still impinging, detailed measurements could be made of the solidified cavity shape. Streamline tests were then made within and above some of these cavities. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Theory of Jets in Ideal Fluids focuses on the use of hydrodynamics in the theory of jets in ideal fluids. The publication first offers information on the introduction to the theory of plane and steady jet flows and flow from a vessel. Discussions focus on flow from a rectangular vessel with an orifice at a corner; vessel with a funnel-shaped bottom and Borda's nozzle; flow from the opening between two flat plates; and Kirchhoff's method. The text then examines infinite flow past a polygonal obstacle, flow around curvilinear obstacles, and flow around a body at small cavitation number. Topics include cavitating flow around a circular cylinder; cavitating flow around a thin profile at an arbitrary angle of attack; cavitating flow around a flat plate; Villat's integro-differential equation and the existence and uniqueness of the solution; and flow past a plate with the separation from its upper surface. The book takes a look at the flow of a heavy fluid and the effects of surface tension, axisymmetric flow, jet flow of compressible fluid, and unsteady flows. The publication is a dependable reference for hydrodynamicists wanting to explore the theory of jets in ideal fluids.

Available in PDF, EPUB and Kindle. Book excerpt: Actuators capable of producing large amplitude oscillations at desired frequencies are needed in many flow control applications. In this dissertation, turbulent jets were actuated using self-sustaining oscillations in axisymmetric cavities. Tested geometries include baseline turbulent jets passing through axisymmetric cavities, with and without peripheral walls. Cavity length to depth ratio (L [subscript c]/D[subscript c]) was varied from 1 to 5 and data were collected at several intermediate steps. Tests were performed with air over a Reynolds number, based on jet exit diameter, range of 40,000 to 225,000 in low to high subsonic jet flow conditions. Pressure signals, 2D velocity data obtained using Particle Image Velocimetry (PIV) and 2D axisymmetric Computational Fluid Dynamics (CFD) modeling were concurrently used to analyze and understand the problem. Measurements on baseline turbulent jets showed that the near field coherent structures and their residence time are two important factors that could be manipulated to influence the initial growth rate of a jet. Frequency of oscillation of the pressure field within the cavity was primarily dependent on the length scale (length to depth ratio and the pipe diameter) of the cavity and the Mach number of the flow. Axisymmetric cavities with cavity length to depth ratio 1.5 - 2.0, preferably 1.75, placed immediately after the exit of the jet exhibited a resonant condition (between the axial shallow cavity mode and the radial acoustic mode of the pipe) with very high amplitude oscillations (in excess of 180 dB within the cavity) at moderate to high Reynolds number range of this study. Comparison with baseline jets based on centerline velocity decay and lateral jet spread rate showed that mixing characteristics had improved significantly. The potential core length (location of 90% jet exit velocity) for the best case was at 1D as compared to 5D for the baseline jet. Ensemble averages of different phases of an oscillation cycle (along the jet flow direction and in the cross-section) were used to recreate the oscillation cycle (flow visualization images, velocity and vorticity fields) and study the flow structures in the near field. Mode of oscillation (axial / helical) of the jet exiting the cavity was found to be dependent on the inlet and exit boundary conditions of the cavity. Cavities with sharp orifices at the inlet and exit boundaries had complex helical mode structures in the near field of the jet. When the exit boundary of the cavity had a short pipe instead of a sharp orifice, only axial mode vortex rings remained in the near field. However the jet entrainment was not as high, as in the case of sharp orifices.

Available in PDF, EPUB and Kindle. Book excerpt: This textbook gives an introduction to fluid dynamics based on flows for which analytical solutions exist, like individual vortices, vortex streets, vortex sheets, accretions disks, wakes, jets, cavities, shallow water waves, bores, tides, linear and non-linear free-surface waves, capillary waves, internal gravity waves and shocks. Advanced mathematical techniques ("calculus") are introduced and applied to obtain these solutions, mostly from complex function theory (Schwarz-Christoffel theorem and Wiener-Hopf technique), exterior calculus, singularity theory, asymptotic analysis, the theory of linear and nonlinear integral equations and the theory of characteristics. Many of the derivations, so far contained only in research journals, are made available here to a wider public.
