Book Synopsis Vortex wakes of Aircrafts by : A.S. Ginevsky
Download or read book Vortex wakes of Aircrafts written by A.S. Ginevsky and published by Springer Science & Business Media. This book was released on 2009-07-07 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Investigation of vortex wakes behind various aircraft, especially behind wide bodied and heavy cargo ones, is of both scientific and practical in terest. The vortex wakes shed from the wing’s trailing edge are long lived and attenuate only atdistances of10–12kmbehindthe wake generating aircraft. The encounter of other aircraft with the vortex wake of a heavy aircraft is open to catastrophic hazards. For example, air refueling is adangerous operationpartly due to thepossibility of the receiver aircraft’s encountering the trailing wake of the tanker aircraft. It is very important to know the behavior of vortex wakes of aircraft during theirtakeoff andlanding operations whenthe wakes canpropagate over the airport’s ground surface and be a serious hazard to other depart ing or arriving aircraft. This knowledge can help in enhancing safety of aircraft’s movements in the terminal areas of congested airports where the threat of vortex encounters limits passenger throughput. Theoreticalinvestigations of aircraft vortex wakes arebeingintensively performedinthe major aviationnations.Usedforthispurpose are various methods for mathematical modeling of turbulent flows: direct numerical simulation based on the Navier–Stokes equations, large eddy simulation using the Navier–Stokes equations in combination with subrigid scale modeling, simulation based on the Reynolds equations closed with a differential turbulence model. These approaches are widely used in works of Russian and other countries’ scientists. It should be emphasized that the experiments in wind tunnels and studies of natural vortex wakes behind heavy and light aircraft in flight experiments are equally important.
Book Synopsis Boundary Integral Methods by : Luigi Morino
Download or read book Boundary Integral Methods written by Luigi Morino and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 533 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains edited papers from IABEM-90, the 1990 Symposium of the Interna tional Association for Boundary Element Methods (IABEM). As stated in the By-Laws of the Association, the purposes of IABEM are: 1. to promote the international exchange of technical information related to the devel opment and application of boundary-integral equation (BIE) formulations and their numerical implementation to problems in engineering and science, commonly referred to as the boundary element method (BEM); 2. to promote research and development activities for the advancement of boundary integral equation methods and boundary element solution algorithms; 3. to foster closer personal relationships within the BEM community of researchers. The objectives of the Symposium, in line with those of the Association, was to provide a forum where the two "souls" of the Association, i. e. , (i) mathematical foundations and numerical aspects, and (ii) engineering applications could be integrated. We believe that the first aspect has been neglected in too many of the BEM Symposia held in the past, which, with a few exceptions (notably, the IUTAM Symposia on the subject) have emphasized the practical aspects of the method. As a consequence, we have tried to give a stronger emphasis to the more theoretical issues: this is attested for instance, by the fact that the two general lectures were given by Prof. Gaetano Fichera, of the University of Rome "La Sapienza," and Prof.

Book excerpt: Available literature has demonstrated a scarcity of data collected behind simple, academic wings that were not NACA profiles. Additionally, comparison of the simplified vortex models is typically performed piecewise without a broad comparison between models. In the present investigation, the structure of an isolated wake vortex is studied and a more thorough comparison of wake vortex models is performed. Experimental data is presented that primarily focuses on the vortex generated by a flat-plate wing. Additional data for a NACA 0015 wing of similar aspect ratio is investigated to validate the experimental method. The experimental method presented utilizes a linear two-axis traverse to position a conventional seven-hole probe in the wake of the generating wing. A semi-span model is used to generate the vortex. Twenty-two vortex surveys are presented between four and sixteen chord lengths downstream of the trailing edge of the generating wing. Vortex core circulation ranges from 8 × 104 to 66 × 104. Vortices presented exhibit a faster decay in peak tangential velocity than reported in some experimental data, but circulation within the core region is shown to remain constant. Comparisons of the current experimental data and simplified models suggests that both the flat plate and NACA 0015 models produce a turbulent vortex. Evidence is presented that suggests that vortex circulation is not the only governing factor on whether a vortex exhibits a laminar or turbulent profile. Fourteen axisymmetric vortex models are considered and their circulation, tangential velocity, and vorticity distributions compared. Both laminar and turbulent models are considered. Discussion is presented on the relationship of vortex circulation and the transition from a laminar to turbulent character. Comparisons highlight a common trend of increased tangential velocity in turbulent vortices at larger radii for the same vortex strengths. Some models estimate unbounded circulation, particularly among turbulent formulations.
