One cannot overemphasize the importance of studying fluids in motion or at rest for a variety of scientific and engineering endeavors. Fluid mechanics as an art reaches back into antiquity, but its rational formulation is a relatively recent undertaking. Much of the physics of a particular flow situation can be understood by conducting appropriate experiments. Flow visualization techniques offer a useful tool to establish an overall picture of a flow field and to delineate broadly its salient features before embarking on more detailed quantitative measurements. Among the single-point measurements that are particularly difficult are those in separated flows, non-Newtonian fluids, rotating flows, and nuclear aerosols. Pressure, shear stress, vorticity, and heat transfer coefficient are also difficult quantities to measure, particularly for time-dependent flows. These and other special situations are among the topics covered in this volume. Each article emphasizes the development of a particular measuring technique. The topics covered were chosen because of their importance to the field, recent appeal, and potential for future development. The articles are comprehensive and coverage is pedagogical with a bias towards recent developments.

Flow meters measure the volumetric flow rate in a pipeline. Most meters are based on deriving a signal from the fluid flow and calibrating the signal against the volumetric flow rate. The calibration is done in fully-developed flow, and the same state of flow must exist at the meter’s position when it is in practical use. Because the field of flow metering has been neglected by fluid mechanicists for a long time, this book addresses two major fluid mechanical problems in flow metering: the analysis of signal generation in turbulent pipe flow, which explains the function of the meter beyond a simple calibration, and the possible use of a meter in non-developed flows. These problems are investigated with reference to, and examples from, a variety of meters, e.g. ultrasound cross-correlation meters, vortex meters, and turbine meters. Studying these problems requires consideration of specific phenomena in turbulent non-developed pipe flow, as caused by installations, and finding special solutions with signal processing, both of which are included in the book.

Accuracy in the laboratory setting is key to maintaining the integrity of scientific research. Inaccurate measurements create false and non-reproducible results, rendering an experiment or series of experiments invalid and wasting both time and money. This handy guide to solid, fluid, and thermal measurement helps minimize this pitfall through careful detailing of measurement techniques. Concise yet thorough, Mechanical Variables Measurement-Solid, Fluid, and Thermal describes the use of instruments and methods for practical measurements required in engineering, physics, chemistry, and the life sciences.

As an engineer, scientist, designer, manager, researcher, or student, you encounter the problem of measurement often and realize that doing it correctly is pivotal to the success of an experiment. This is the first place to turn when deciding on, performing, and troubleshooting the measurement process. Mechanical Variables Measurement-Solid, Fluid, and Thermal leads the reader, step-by-step, through the straits of experimentation to triumph.

An Introduction to Turbulence and Its Measurement is an introductory text on turbulence and its measurement. It combines the physics of turbulence with measurement techniques and covers topics ranging from measurable quantities and their physical significance to the analysis of fluctuating signals, temperature and concentration measurements, and the hot-wire anemometer. Examples of turbulent flows are presented. This book is comprised of eight chapters and begins with an overview of the physics of turbulence, paying particular attention to Newton's second law of motion, the Newtonian viscous fluid, and equations of motion. After a chapter devoted to measurable quantities, the discussion turns to some examples of turbulent flows, including turbulence behind a grid of bars, Couette flow, atmospheric and oceanic turbulence, and heat and mass transfer. The next chapter describes measurement techniques using hot wires, films, and thermistors, as well as Doppler-shift anemometers; glow-discharge or corona-discharge anemometers; pulsed-wire anemometer; and steady-flow techniques for fluctuation measurement. This monograph is intended for post-graduate students of aeronautics and fluid mechanics, but should also be readily understandable to those with a good general background in engineering fluid dynamics.
