Book excerpt: An experimental study of the effects of spatially-limited (i.e. localized) surface suction on unsteady laminar and turbulent junction flows was performed using hydrogen bubble flow visualization and Particle Image Velocimetry (PIV). Results indicate that suction on the laminar system can effectively modify the flow topology and periodicity. Detailed analysis of laminar PIV results indicates that it is the impinging boundary layer instability which is the mechanism for vortex generation frequency in the unsteady laminar case. Application of external perturbations to the impinging boundary layer can be used to initiate 'lock-on' of the vortex formation frequency to the forcing frequency over a narrow range of frequencies. PIV results of turbulent junction flow indicate that surface suction effectively weakens both the instantaneous turbulent vortex and the associated surface interactions on the symmetry plane, can eliminate the average turbulent necklace vortex on the symmetry plane, and weakens the average downstream strength of the vortex. It was also determined that suction effectively reduces the Reynolds-stress levels in both the symmetry plane and cross-stream planes, as well as reducing the unsteady behavior of the turbulent vortex legs.

Book excerpt: PIV results of turbulent junction flow indicate that surface suction effectively weakens the instantaneous turbulent vortex and associated surface interactions on the symmetry plane, can eliminate the average turbulent necklace vortex on the symmetry plane, and weaken the average downstream extensions of the vortex. It was also found that suction effectively reduces the Reynolds-stress levels on the symmetry plane and the medial and trailing edge cross-stream planes. In addition, the unsteady motion of the turbulent vortex legs is reduced by application of suction.

This book was released on 2008-11-25 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Reliability and Risk Issues in Large Scale Safety-critical Digital Control Systems” provides a comprehensive coverage of reliability issues and their corresponding countermeasures in the field of large-scale digital control systems, from the hardware and software in digital systems to the human operators who supervise the overall process of large-scale systems. Unlike other books which examine theories and issues in individual fields, this book reviews important problems and countermeasures across the fields of software reliability, software verification and validation, digital systems, human factors engineering and human reliability analysis. Divided into four sections dealing with software reliability, digital system reliability, human reliability and human operators in large-scale digital systems, the book offers insights from professional researchers in each specialized field in a diverse yet unified approach.

This book was released on 2003-03-31 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: The IUTAM Symposium on Flow in Collapsible Tubes and Past Other Highly Compliant Boundaries was held on 26-30 March, 2001, at the University of Warwick. As this was the first scientific meeting of its kind we considered it important to mark the occasion by producing a book. Accordingly, at the end of the Symposium the Scientific Committee met to discuss the most appropriate format for the book. We wished to avoid the format of the conventional conference book consisting of a large number of short articles of varying quality. It was agreed that instead we should produce a limited number of rigorously refereed and edited articles by selected participants who would aim to sum up the state of the art in their particular research area. The outcome is the present book. Peter W. Ca rpenter, Warwick Timothy J. Pedley, Cambridge May, 2002. VB SCIENTIFIC COMMITTEE Co-Chair: P.W. Carpenter, Engineering, Warwiek, UK Co-Chair: TJ.

Download or read book Advances in Modeling and Management of Urban Water Networks written by Alberto Campisano and published by MDPI. This book was released on 2021-01-06 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Special Issue on Advances in Modeling and Management of Urban Water Networks (UWNs) explores four important topics of research in the context of UWNs: asset management, modeling of demand and hydraulics, energy recovery, and pipe burst identification and leakage reduction. In the first topic, the multi-objective optimization of interventions on the network is presented to find trade-off solutions between costs and efficiency. In the second topic, methodologies are presented to simulate and predict demand and to simulate network behavior in emergency scenarios. In the third topic, a methodology is presented for the multi-objective optimization of pump-as-turbine (PAT) installation sites in transmission mains. In the fourth topic, methodologies for pipe burst identification and leakage reduction are presented. As for the urban drainage systems (UDSs), the two explored topics are asset management, with a system upgrade to reduce flooding, and modeling of flow and water quality, with analyses on the transition from surface to pressurized flow, impact of water use reduction on the operation of UDSs, and sediment transport in pressurized pipes. The Special Issue also includes one paper dealing with the hydraulic modeling of an urban river with a complex cross-section.
