This book was released on 1971 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: A three-dimensional numerical solution of the time-dependent, incompressible Navier-Stokes equations based on an integro-differential formulation of these equations is developed. With this formulation it is possible to obtain the complete solution in the entire flow field while restricting the actual computational field to the region of significant vorticity magnitude of each time. This allows a considerable reduction in the computer storage required, since only the field points having significant vorticity at any time need be stored at that time, and calculations are actually performed only at those points at that time. The validity of the numerical solution is established by comparison of the results with the exact solution for the time-dependent, one-dimensional flow over a suddenly accelerated infinite flat plate moving parallel to itself at constant velocity, and by comparison of surface pressure and drag coefficients with experimental results, and with the results of other numerical solutions for the two-dimensional flow about a circular cylinder. The numerical solution is applied to the flow field of an infinite jet in a cross-flow and to the flow field of a jet issuing perpendicularly from an infinite plane wall into a cross-flow parallel to the wall.

Available in PDF, EPUB and Kindle. Book excerpt: A semiempirical theory on the bending and development of a round turbulent jet in a subsonic crosswind is presented. A theoretical model of dynamical interaction between the jet and external flow has been formulated by combining an entrainment model and a vortex sheet model, taking into account the inward flow of air outside into the jet induced by a pair of concentrated vortices on the rear side of the jet. The mass inflow rate is related to the moment of the vortex-doublet. (Author).

This book was released on 1973 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation has been undertaken to develop a theoretical model of the incompressible jet injection process. The discharge of a turbulent jet into a cross flow was mathematically modeled by using an integral method which accounts for natural fluid mechanisms such as turbulence, entrainment, buoyancy, and heat transfer. The analytical results are supported by experimental data and demonstrate the usefulness of the theory for estimating the trajectory and flow properties of the jet for a variety of injection conditions. The capability of predicting jet flow properties, as well as two- and three- dimensional jet paths, was enhanced by obtaining the jet cross-sectional area during the solution of the conservation equations (a number of previous studies assume a specific growth for the area). Realistic estimates of temperature in the jet fluid were acquired by accounting for heat losses in the jet flow due to forced convection and to entrainment of free-stream fluid into the jet.

This book was released on 2012-12-06 with total page 752 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Joint Institute for Aeronautics and Acoustics at Stanford University was established in October 1973 to provide an academic environment for long-term cooperative research between Stanford and NASA Ames Research Center. Since its establishment, the In stitute has wnducted theoretical and experimental work in the areas of aerodynamics, acoustics, fluid mechanics, flight dynamics, guid ance and control, and human factors. This research has involved Stanford faculty, research associates, graduate students, and many distinguished visitors in collaborative efforts with the research staff of NASA Ames Research Center. The occasion of the Institute's tenth anniversary was used to reflect back on where that research has brought us, and to consider where our endeavors should be directed next. Thus, an International Symposium was held to review recent advances in the fields relevant to the activities of the Institute and to discuss the areas of research to be undertaken in the future. This anniversary was also chosen a.."1 an opportunity to honor one of the Institute's founders and its di rector, Professor Krishnamurty Karamcheti. It has been his creative inspiration that has provided the ideal research environment at the Joint Institute. The International Symposium on Recent Advances in Aero dynamics and Aconstics was held at Stanford University, Stanford, California, U.S.A., August 22-26, 198:~. Thirty-five distinguished scientists were invited to present a comprehensive review on the fol lowing subject areas: unsteady aerodynamics, jets and shear layers, V /STOL aircraft aerodynamics, rotor dynamics and aerodynamics,.

This book was released on 1970 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of a jet exhausting normally from an infinite flat plate into a crosswind is studied analytically, primarily in terms of the resulting interference pressures on the plate. Three jet exit shapes are considered: a circle; an ellipse with the major axis aligned with the crosswind (streamwise exist); and an ellipse with the major axis perpendicular to the crosswind (blunt exit). It is shown that a two-dimensional steady potential flow model for the crosswind in planes parallel to the plate may be used, provided the jet-to-crosswind speed ratio is sufficiently large and the wake region is excluded. A blockage-sink model is developed wherein the blockage elements represent blockage due to the jet plume and due to the presence of the wake and a single sink represents entrainment. The model parameters are presented as functions of speed ratio and jet exist thickness ratio. The blockage and entrainment parameters are varied over a range of values to determine the effects of each on the interference pressure, and it is found that the entrainment factor is quite significant. The streamwise and circular jet exits are more useful for lifting-jet applications than the blunt exit because of their favorable coupling of the blockage and entrainment effects and their relatively small wake production.
