Available in PDF, EPUB and Kindle. Book excerpt: Shock wave-boundary-layer interaction (SBLI) is a fundamental phenomenon in gas dynamics that is observed in many practical situations, ranging from transonic aircraft wings to hypersonic vehicles and engines. SBLIs have the potential to pose serious problems in a flowfield; hence they often prove to be a critical - or even design limiting - issue for many aerospace applications. This is the first book devoted solely to a comprehensive, state-of-the-art explanation of this phenomenon. It includes a description of the basic fluid mechanics of SBLIs plus contributions from leading international experts who share their insight into their physics and the impact they have in practical flow situations. This book is for practitioners and graduate students in aerodynamics who wish to familiarize themselves with all aspects of SBLI flows. It is a valuable resource for specialists because it compiles experimental, computational and theoretical knowledge in one place.

Download or read book On the Scaling and Unsteadiness of Shock Induced Separation written by Louis Jacques Souverein and published by . This book was released on with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shock wave boundary layer interactions (SWBLI) are a common phenomenon in transonic and supersonic flows. The presence of shock waves, induced by specific geometrical configurations, cause a rapid increase of the pressure, wich can lead to flow separation. Examples of such interaction are found in amongts other rocket engine nozzles, on re-entry vehicles, in supersonic and hypersonic engine intakes, and at the tips of compressor and turbine blades. The interactions are important factors in vehicle development. Both the separated flow and the induced shock have been shows to be highly unsteady, causing pressure fluctuations and thermal loading. This generally leads to a degraded performance and possibly structural failure. The current work therefore aims to improve the physical understanding of the mechanisms that govern the interaction, with a special attention for the flow organisation and for the sources of the unsteadiness of the induced shock. Additioinally, it is verified wether the interaction can be controlled by means of upstream fluid injection. PIV measurements were performed, comparing several interactions for a range of shock intensities for a number of Mach and Reynolds numbers. It is proposed that relative importance of the different unsteadiness mechanisms (upstream, downstream) shifts with the imposed shock intensity. The onset of separation is Reynolds number independent for turbulent boundary layers. The interaction length is however governed by the both the Reynolds number and the Mach number.

Download or read book An Experimental Study of Coherent Structures in Shock Boundary Layer Interaction at Mach 3 written by Narendra Chaganti Subrahmanya Datta and published by . This book was released on 2017 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: The flow structure and unsteadiness of Shockwave-Boundary Layer Interaction (SWBLI) has been studied using Rainbow Schlieren Deflectometry (RSD), Ensemble Averaging, Fast Fourier Transform (FFT), snapshot Proper Orthogonal Decomposition (POD) and Dynamic Mode Decomposition (DMD) techniques. The Mach number of the approach free-stream was Mach = 3.1. The shockwave was generated with a 12° isosceles triangular prism attached to the roof of the test section. The RSD pictures were obtained with high speed cameras both at 5,000 frames per second (fps) and 30,000 fps; RSD images were used to determine the transverse ray deflections at each pixel location of the pictures. The objectives of this research were a) to identify the flow structures of SWBLI, b) to identify the frequencies of the unsteady flow in the SWBLI and c) infer the link between different regions of the flow using the obtained characteristic frequencies. The interaction region flow structure was described statistically with the ensemble average and, root mean square deflections. FFT technique was used to determine the frequency content of the flow field. The frequencies and associated spectral power were used in studying the flow unsteadiness and the energy scales of the flow were studied to obtain the dominant frequencies. Coherence function was used to identify coherent structures present in the flow field and their corresponding frequencies. The POD technique was used to determine the dominant flow structures in accordance with their energy content. POD results complement the findings of the ensemble averaging technique and show distinct regions that contain most of the energy in the flow field. Dynamic Mode Decomposition (DMD) study was used to identify the complex nature of the interactions. Utilization of DMD gave frequency content of the flow field which was missing from snapshot POD. The analysis was concentrated on the regions of interest which were in the vicinity of the separation bubble including the incident, transmitted, separation and reflected shock regions. Stable modes were obtained, and based on the peaks of global energy norm, respective frequencies were obtained. Dominant flow fields were reconstructed based on the obtained frequency peaks. The dominant frequencies and coherent structures obtained using FFT, coherence, snapshot POD and DMD were compared to yield common set of information.

This book was released on 2020-07-30 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents experimental and numerical findings on reducing shock-induced separation by applying transition upstream the shock wave. The purpose is to find out how close to the shock wave the transition should be located in order to obtain favorable turbulent boundary layer interaction. The book shares findings obtained using advanced flow measurement methods and concerning e.g. the transition location, boundary layer characteristics, and the detection of shock wave configurations. It includes a number of experimental case studies and CFD simulations that offer valuable insights into the flow structure. It covers RANS/URANS methods for the experimental test section design, as well as more advanced techniques, such as LES, hybrid methods and DNS for studying the transition and shock wave interaction in detail. The experimental and numerical investigations presented here were conducted by sixteen different partners in the context of the TFAST Project. The general focus is on determining if and how it is possible to improve flow performance in comparison to laminar interaction. The book mainly addresses academics and professionals whose work involves the aerodynamics of internal and external flows, as well as experimentalists working with compressible flows. It will also be of benefit for CFD developers and users, and for students of aviation and propulsion systems alike.
