Download and read online Numerische Simulation des Ger usches massiv abgel ster Str mung bei gro er Reynoldszahl und kleiner Machzahl in PDF and EPUB Strömungsinduzierte Geräusche stellen heute ein zunehmendes Problem dar, besonders in der Umgebung von Flughäfen. Eine flächendeckende Lärmminderung ließe sich hier in erster Linie durch konstruktive Maßnahmen zur Abschwächung der wesentlichen Schallentstehungsmechanismen am Flugzeug erzielen. Dies setzt jedoch voraus, dass verlässliche aeroakustische Vorhersagen getroffen werden können, wozu nicht nur präzise Berechnungsverfahren für die Schallausbreitung, sondern auch für das mittlere Strömungsfeld und für die aerodynamischen Geräuschquellen erforderlich sind. In der vorliegenden Arbeit wird ein im Bereich subsonischer Strömungssimulationen etabliertes, druckbasiertes 3D-Finite-Volumen-Verfahren für den Einsatz in aeroakustischen Grobstruktursimulationen weiterentwickelt. Der hier vordergründig betrachtete Strömungszustand und Kennzahlbereich ist typisch für das Entstehen von „airframe noise“, aerodynamischem Lärm, welcher primär durch die turbulente Umströmung von Fahrwerk und Hochauftriebshilfen startender oder landender Flugzeuge verursacht wird. Die Kopplung von kompressiblen Grobstruktursimulationen im Quellgebiet mit nachgeschalteten akustischen Extrapolationen ermöglicht eine Berechnung dieser Umströmungsgeräusche bis ins Fernfeld. Nach kurzer Darstellung der physikalischen Grundlagen und verschiedener Möglichkeiten zur numerischen Simulation wird das ausgewählte Verfahren im Detail analysiert und eine Schwachstelle in der zur Berechnung der Massenflüsse eingesetzten Interpolation nach Rhie & Chow identifiziert. Der Schwerpunkt der Weiterentwicklung liegt anschließend auf der sorgfältigen Herleitung einer Familie konsistenter Approximationen zur Bestimmung von Massenflüssen über Kontrollvolumengrenzflächen auf nichtversetzten Gittern. Zwei neue Varianten der Massenflussberechnung werden in das bestehende Druckkorrekturverfahren integriert. Deren Verhalten wird im Vergleich zur ursprünglichen Implementierung an einem akademischen Testfall bewertet. Es folgt eine Abstimmung von Numerik und Feinstrukturmodell am Zerfall isotroper Turbulenz und nach der Qualifizierung des verbesserten Verfahrens schließlich dessen Anwendung zur Berechnung von Strömungsgeräuschen an einer generischen Fahrwerksverstrebung und an einer 3-Komponenten-Hochauftriebskonfiguration. Die Ergebnisse dieser Simulationen weisen überwiegend eine sehr gute Übereinstimmung mit experimentell ermittelten Daten auf. Auf Basis einer aeroakustischen Analyse der hochaufgelösten Simulationsergebnisse am Vorflügel gelingt letztlich ein statistischer Nachweis für den dort dominierenden Schallentstehungsmechanismus. Flow-induced noise represents an increasing problem today, particularly in the vicinity of airports. Comprehensive aircraft noise reduction could primarily be achieved through design changes which mitigate the major noise generation mechanisms. However, such changes require reliable aeroacoustic predictions, which is only possible if appropriate numerical tools are available. These must allow the precise calculation of the sound and mean flow fields as well as the most relevant aerodynamic noise sources. In this work a pressure-based 3D finite volume method, which is already well-established in the area of subsonic flow computation, is further developed in order to enable its application for aeroacoustic large-eddy simulations. The flow state and the range of similarity parameters considered here are chosen to be representative of typical airframe noise. This is mainly caused by separated flow around deployed landing gear and high-lift devices during aircraft takeoff and landing. The coupling of compressible large-eddy simulations in the main sound source regions with subsequent acoustic extrapolations provides access to the prediction of such aerodynamic noise up to the farfield. The selected method is analysed in detail following a brief overview of the physical background and state-of-the-art numerical simulation techniques. A weak point is identified in the Rhie & Chow interpolation which is employed for the calculation of mass fluxes. Particular emphasis is then placed on the careful derivation of a family of consistent approximations for the determination of mass flux over control volume faces on co-located grids. Two new flux formulations are integrated into the existing pressure correction method. Their behaviour is validated and compared to that of the original implementation on an academic test case. Following a thorough reassessment of the balance between numerical and modelled dissipation on the decay of isotropic turbulence, the improved method is finally applied to compute the flow-induced noise around a generic two-struts configuration and around a three-component high-lift configuration. The simulation results predominantly exhibit very good agreement with experimental data. Based on highly-resolved flow field data acquired from the simulation of the high-lift system, a concise aeroacoustic analysis is offered. Statistical evidence of the dominant noise generation mechanism near a leading edge slat is provided.

Download and read online Computational Fluid Dynamics in PDF and EPUB This book is an outgrowth of a von Kannan Institute Lecture Series by the same title first presented in 1985 and repeated with modifications in succeeding years. The objective, then and now, was to present the subject of computational fluid dynamics (CFD) to an audience unfamiliar with all but the most basic aspects of numerical techniques and to do so in such a way that the practical application ofCFD would become clear to everyone. Remarks from hundreds of persons who followed this course encouraged the editor and the authors to improve the content and organization year by year and eventually to produce the present volume. The book is divided into two parts. In the first part, John Anderson lays out the subject by first describing the governing equations offluid dynamics, concentration on their mathematical properties which contain the keys to the choice of the numerical approach. Methods of discretizing the equations are discussed next and then transformation techniques and grids are also discussed. This section closes with two examples of numerical methods which can be understood easily by all concerned: source and vortex panel methods and the explicit method. The second part of the book is devoted to four self-contained chapters on more advanced material: Roger Grundmann treats the boundary layer equations and methods of solution; Gerard Degrez treats implicit time-marching methods for inviscid and viscous compressible flows, and Eric Dick treats, in two separate articles, both finite-volume and finite-element methods.

Download and read online Fundamental Mechanics of Fluids Fourth Edition in PDF and EPUB Fundamental Mechanics of Fluids, Fourth Edition addresses the need for an introductory text that focuses on the basics of fluid mechanics—before concentrating on specialized areas such as ideal-fluid flow and boundary-layer theory. Filling that void for both students and professionals working in different branches of engineering, this versatile instructional resource comprises five flexible, self-contained sections: Governing Equations deals with the derivation of the basic conservation laws, flow kinematics, and some basic theorems of fluid mechanics. Ideal-Fluid Flow covers two- and three-dimensional potential flows and surface waves. Viscous Flows of Incompressible Fluids discusses exact solutions, low-Reynolds-number approximations, boundary-layer theory, and buoyancy-driven flows. Compressible Flow of Inviscid Fluids addresses shockwaves as well as one- and multidimensional flows. Methods of Mathematical Analysis summarizes some commonly used analysis techniques. Additional appendices offer a synopsis of vectors, tensors, Fourier series, thermodynamics, and the governing equations in the common coordinate systems. The book identifies the phenomena associated with the various properties of compressible, viscous fluids in unsteady, three-dimensional flow situations. It provides techniques for solving specific types of fluid-flow problems, and it covers the derivation of the basic equations governing the laminar flow of Newtonian fluids, first assessing general situations and then shifting focus to more specific scenarios. The author illustrates the process of finding solutions to the governing equations. In the process, he reveals both the mathematical methodology and physical phenomena involved in each category of flow situation, which include ideal, viscous, and compressible fluids. This categorization enables a clear explanation of the different solution methods and the basis for the various physical consequences of fluid properties and flow characteristics. Armed with this new understanding, readers can then apply the appropriate equation results to deal with the particular circumstances of their own work.

Download and read online Fluid Dynamics with a Computational Perspective in PDF and EPUB Modern fluid dynamics is a combination of traditional methods of theory and analysis and newer methods of computation and numerical simulation. Fluid Dynamics with a Computational Perspective synthesizes traditional theory and modern computation. It is neither a book on methods of computation, nor a book on analysis; it is about fluid dynamics. The book is ideal for a course on fluid dynamics. Early chapters review the laws of fluid mechanics and survey computational methodology, following chapters study flows in which the Reynolds number increases from creeping flow to turbulence, followed by a thorough discussion of compressible flow and interfaces. Whereas all significant equations and their solutions are presented, their derivations are informal. References for detailed derivations are provided. A chapter on intermediate Reynolds number flows provides illustrative case studies by pure computation. Elsewhere, computations and theory are interwoven.
