Binnen het HBO wordt steeds meer een beroep gedaan op zelfstudie. Daardoor stijgt de behoefte aan leerboeken, waarin eenvoudig fysisch inzicht als uitgangspunt dient. Dit boek gaat uit van eenvoudige natuurkundige basisprincipes, waarbij bewust vermeden is om verbanden eerst in zeer algemene zin af te leiden. De gekozen opzet maakt het boek ook uitermate geschikt voor geïnteresseerden uit de praktijk die zich de belangrijkste aspecten van de stromingsleer eigen willen maken. De stof uit het vroegere deel 1 is nu uitgebreid met een paragraaf over dimensie-analyse, een belangrijk hulpmiddel bij het beschrijven van stromingstechnische verschijnselen waarin veel invloedsgrootheden een rol spelen. Bovendien is een hoofdstuk Stroming van compressibele fluïda opgenomen, waarin de theorie wordt behandeld van stroming door leidingen, verschijnselen die samenhangen met de geluidssnelheid en expansie in straalbuizen.

The book deals with modern methods of nonlinear stability theory applied to problems of continuous media mechanics in the presence of interfaces, with applications to materials science, chemical engineering, heat transfer technologies, as well as in combustion and other reaction-diffusion systems. Interfaces play a dominant role at small scales, and their correct modeling is therefore also crucial in the rapidly expanding fields of microfluidics and nanotechnologies. To this aim, the book combines contributions of eminent specialists in the field, with a special emphasis on rigorous and predictive approaches. Other goals of this volume are to allow the reader to identify key problems of high scientific value, and to see the similarity between a variety of seemingly different physical problems.

The seventh ERCOFTAC Workshop on "Direct and Large-Eddy Simulation" (DLES-7) was held at the University of Treste from September 8-10, 2008. Following the tradition of previous workshops in the DLES-series this edition reflects the state of the art of numerical simulation of traditional and turbulent flows and provided an active forum for discussion of recent developments in simulation techniques and understanding of flow physics. At a fundamental level this workshop addressed numerous theoretical and physical aspects of transitional and turbulent flows. At an applied level it contributes to the solution of problems related to energy production, transportation and the environment. This book is of interest to scientists and engineers both at an early level in their career as well as at more senior levels.

This book gathers the proceedings of the 12th instalment in the bi-annual Workshop series on Direct and Large Eddy Simulation (DLES), which began in 1994 and focuses on modern techniques used to simulate turbulent flows based on the partial or full resolution of the instantaneous turbulent flow structure. With the rapidly expanding capacities of modern computers, this approach has attracted more and more interest over the years and will undoubtedly be further enhanced and applied in the future. Hybrid modelling techniques based on a combination of LES and RANS approaches also fall into this category and are covered as well. The goal of the Workshop was to share the state of the art in DNS, LES and related techniques for the computation and modelling of turbulent and transitional flows. The respective papers highlight the latest advances in the prediction, understanding and control of turbulent flows in academic and industrial applications.

This book introduces novel methods for leak and blockage detection in pipelines. The leak happens as a result of ageing pipelines or extreme pressure forced by operational error or valve rapid variation. Many factors influence blockage formation in pipes like wax deposition that leads to the formation and eventual growth of solid layers and deposition of suspended solid particles in the fluids. In this book, initially, different categories of leak detection are overviewed. Afterwards, the observability and controllability of pipeline systems are analysed. Control variables can be usually presented by pressure and flow rates at the start and end points of the pipe. Different cases are considered based on the selection of control variables to model the system. Several theorems are presented to test the observability and controllability of the system. In this book, the leakage flow in the pipelines is studied numerically to find the relationship between leakage flow and pressure difference. Removing leakage completely is almost impossible; hence, the development of a formal systematic leakage control policy is the most reliable approach to reducing leakage rates.

This book aims to show how hemodynamic numerical models based on Computational Fluid Dynamics (CFD) can be developed. An approach to Fluid Mechanics is made from a historical point of view focusing on the Navier-Stokes Equations and a fluid-mechanical description of blood flow. Finally, the techniques most used to visualize cardiac flows and validate numerical models are detailed, paying special attention to Magnetic Resonance Imaging (MRI) in case of an in vivo validation and Particle Image Velocimetry (PIV) for an in vitro validation.
