Summary and Info
Instrumentation is now supplied as a turnkey apparatus displaying the results of measurements on the screen of a personal computer. Compared to the tedious data handling of the past, this is a wonderful improvement. Despite the shift to automated systems, however, the basic methods and theory have not changed and it is still necessary to understand the basic test techniques and objectives so that tests can be planned and carried out knowing the limits and and the approximations of the instrument used."Aerodynamic measurements" presents a comprehensive review on the theoretical bases on which experimental techniques used in aerodynamics are based. Chapters discuss limitations of each measurement method in terms of accuracy, response time, and complexity. The book will serve as a guide in choosing the most pertinent technique for each type of flow field including: 1D, 2D, 3D, steady or unsteady, subsonic and supersonic of hypersonic. Professor Russo reviews: pressure sensors, velocity and mass flow by pressure measurements, hot wire anemometer, laser anemometry, temperature measurements, flow visualization and measurements of aerodynamic forces.
