Elements Of Transitional Boundary Layer Flowlements

Second Enhanced Edition Suitable for advanced-level courses or an independent study in fluid mechanics, this text by an expert in the field provides the basic aspects of laminar-to-turbulent flow transition in boundary layers. Logically organized into three major parts, the book covers pre- and post-transitional flow, transitional flow, and several advanced topics in periodically disturbed transitional flow. Some of the subjects covered within the book include high-frequency unsteady laminar flow, turbulent flow, natural transition, bypass transition, turbulent spot theory, turbulent spot kinematics and production, correlations for the onset and rate of transition, global and conditional averaging, transitional flow models, wakeinduced transition, multimode transition, and separated-flow transition. Containing some 202 figures (all drawn by the author), 28 tables, 12 appendices, a supplement on tensors, and an extensive bibliography, the 415 page book provides a wealth of data and information about the subject.

This book is an introduction to computational fluid dynamics with emphasis on the solution of the boundary-layer equations and the modeling and computation of boundary-layer flows. It also provides readers with a good understanding of the basic principles of fluid dynamics and numerical methods. A variety of readers, including undergraduate and graduate students, teachers or scientists working in aerodynamics or hydrodynamics will find the text interesting. The subjects covered in this book include laminar and , turbulent boundary layers and laminar--turbulent transition. The viscous--inviscid coupling between the boundary layer and the inviscid flow is also addressed. Two-dimensional and three-dimensional incompressible flows are considered. Physical and numerical aspects of boundary-layer flows are described in detail in 12 chapters. A large number of homework problems are included.

ARIS (Architecture of Integrated Information Systems) is a unique and internationally renowned method for optimizing business processes and implementing application systems. This book enhances the proven ARIS concept by describing product flows and explaining how to classify modern software concepts. The importance of the link between business process organization and strategic management is stressed. Bridging the gap between the different approaches in business theory and information technology, the ARIS concept provides a full-circle approach-from the organizational design of business processes to IT implementation. With an emphasis on SAP R/3, real-world examples of standard software solutions illustrate these business process frameworks.

This volume is an information-packed reference for engineers on flow measuring techniques and instruments. Striking a balance between laboratory ideal and the realities of field experience, this handy tool provides a wealth of practical advice on the design, operation, and performance of a broad range of flowmeters. The book begins with a brief review of fluid mechanics principles, how to select a flowmeter, and a variety of calibration methods. Each of the following chapters is devoted to a class of flowmeters and includes detailed information on design, applications, installation, calibration, operation, and advantages and disadvantages. Among the flowmeters discussed are orifice plate meters, venturi meter and standard nozzles, critical flow venturi nozzles, positive displacement flowmeters, turbine and related flowmeters, vortex shedding and fluidic flowmeters, electromagnetic flowmeters, ultrasonic flowmeters, and coriolis flowmeters. Also covered are mass flow measurements using multiple sensors, thermal flowmeters, angular momentum devices, probes, and modern control systems. Many chapters conclude with an appendix on the theory behind the techniques discussed. It will be a valuable reference for practicing engineers and will also be of interest to researchers in mechanical, chemical and aerospace engineering.

Transactions on Petri Nets and Other Models of Concurrency (ToPNoC) II These Transactions publish archival papers in the broad area of Petri nets and other models of concurrency, ranging from theoretical work to tool support and industrial applications. ToPNoC issues are published as LNCS volumes, and hence are widely distributed and indexed. This Journal has its own Editorial Board which selects papers based on a rigorous two-stage refereeing process. ToPNoC contains: - Revised versions of a selection of the best papers from workshops and tutorials at the annual Petri net conferences - Special sections/issues within particular subareas (similar to those published in the Advances in Petri Nets series) - Other papers invited for publication in ToPNoC - Papers submitted directly to ToPNoC by their authors The second volume of ToPNoC focuses on Concurrency in Process-Aware Information Systems. Although the topic of business process management using information technology has been addressed by consultants and software developers in depth, more fundamental approaches towards such Process-Aware Information Systems (PAISs) have been rather uncommon. It wasn't until the 1990s that researchers started to work on the foundations of PAISs. Clearly, concurrency theory is an essential ingredient in these foundations as business processes are highly concurrent involving all types of routing logic and resource allocation mechanisms. The 16 papers in this special issue of ToPNoC cover topics ranging from the formal (mostly Petri-net based) foundations of PAISs to more applied topics such as flexibility and process mining. Thus, this volume gives a good overview of the state of the art in PAIS research.

Techniques and Topics in Flow Measurement covers the applications and techniques of flow measurement. This definitive book provides guidelines for choosing appropriate techniques and assuring valid measurements as well as describes methods for treatment of calibration data in fluid flow under various conditions. The book also covers three systems of units: the SI system, the English Absolute Dimensional system, and the English Engineering system. Commonly used - and often misused - variables such as force, weight, and pressure are defined, and the relationships between the systems for these common variables are summarized. One of the many unique features of Techniques and Topics in Flow Measurement is the number of ready-to-use tables included throughout the text. Tables are provided for such commonly encountered variables as the saturation vapor pressure of water; the composition of dry air; the compressibility factor for air; air-free and air-saturated water density; viscosity of dry air, nitrogen, and other gases; and specific heat/specific volume ratios for dry air, water vapor, and moist air. Another unique feature of this book is the number of highly relevant examples. The author includes examples/exercises that demonstrate applications for density calculations; water vapor mixing ratio determination; gas viscosity interpolation; NIST guideline applications; buoyancy corrections; and more.

A comprehensive guide to wind farm noise prediction, measurement, assessment, control and effects on people Wind Farm Noise covers all aspects associated with the generation, measurement, propagation, regulation and adverse health effects of noise produced by large horizontal-axis wind turbines of the type used in wind farms. The book begins with a brief history of wind turbine development and the regulation of their noise at sensitive receivers. Also included is an introductory chapter on the fundamentals of acoustics relevant to wind turbine noise so that readers are well prepared for understanding later chapters on noise measurements, noise generation mechanisms, noise propagation modelling and the assessment of the noise at surrounding residences. Key features: Potential adverse health effects of wind farm noise are discussed in an objective way. Means for calculating the noise at residences due to a wind farm prior to construction are covered in detail along with uncertainty estimates. The effects of meteorological conditions and other influences, such as obstacles, ground cover and atmospheric absorption, on noise levels at residences are explained. Quantities that should be measured as well as how to best measure them in order to properly characterise wind farm noise are discussed in detail. Noise generation mechanisms and possible means for their control are discussed as well as aspects of wind farm noise that still require further research to be properly understood. The book provides comprehensive coverage of the topic, containing both introductory and advanced level material.
