Application of Thermo-Fluidic Measurement Techniques


Book Description

Application of Thermo-Fluidic Measurement Techniques: An Introduction provides essential measurement techniques in heat transfer and aerodynamics. In addition to a brief, but physically elaborate description of the principles of each technique, multiple examples for each technique are included. These examples elaborate all the necessary details of (a) test setups, (b) calibration, (c) data acquisition procedure, and (d) data interpretation, with comments on the limitations of each technique and how to avoid mistakes that are based on the authors’ experience. The authors have different expertise in convection heat transfer and aerodynamics, and have collaborated on various research projects that employ a variety of experimental techniques. Each author has a different view and approach to individual experimental techniques, but these views complement each other, giving new users of each technique a rounded view. With the introduction of this valuable reference book, the reader can quickly learn both the overall and detailed aspects of each experimental technique and then apply them to their own work.

Infrared Thermography for Thermo-Fluid-Dynamics


Book Description

Infrared thermography is a measurement technique that enables to obtain non intrusive measurements of surface temperatures. One of the interesting features of this technique is its ability to measure a full two dimensional map of the surface temperature and for this reason it has been widely used as a flow visualization technique. Since the temperature measurements can be extremely accurate it is possible, by using a heat flux sensor, also to measure convective heat transfer coefficient distributions on a surface making the technique de facto quantitative. This book, starting from the basic theory of infrared thermography and heat flux sensor guides, both the experienced researcher and the young student, in the correct application of this powerful technique to various practical problems. A significant number of examples and applications are also examined in detail.




Mechanical Variables Measurement - Solid, Fluid, and Thermal


Book Description

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.

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. Organized according to measurement problem, the entries are easy to access. The articles provide equations to assist engineers and scientists who seek to discover applications and solve problems that arise in areas outside of their specialty. Sections include references to more specialized publications for advanced techniques, as well. It offers instruction for a range of measuring techniques, basic through advanced, that apply to a broad base of disciplines. 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.

Optical Measurements


Book Description

Increasing possibilities of computer-aided data processing have caused a new revival of optical techniques in many areas of mechanical and chemical engi neering. Optical methods have a long tradition in heat and mass transfer and in fluid dynamics. Global experimental information is not sufficient for de veloping constitution equations to describe complicated phenomena in fluid dynamics or in transfer processes by a computer program. Furthermore, a detailed insight with high local and temporal resolution into the thermo and fluiddynamic situations is necessary. Sets of equations for computer program in thermo dynamics and fluid dynamics usually consist of two types of formulations: a first one derived from the conservation laws for mass, energy and momentum, and a second one mathematically modelling transport processes like laminar or turbulent diffusion. For reliably predicting the heat transfer, for example, the velocity and temperature field in the boundary layer must be known, or a physically realistic and widely valid correlation describing the turbulence must be avail able. For a better understanding of combustion processes it is necessary to know the local concentration and temperature just ahead of the flame and in the ignition zone.
