The Aerodynamic Drag On Spheres Under Acceleration, Charles Earl Nielson
The Aerodynamic Drag On Spheres Under Acceleration, Charles Earl Nielson
Theses and Dissertations
The requirement of a greater understanding of the behavior of solids-gas systems has shown itself profoundly with the advancement of science and technology during recent years. The range and variety of processes in which these systems play an important role is exceptionally broad. These processes range from meteorological disturbances such as dust storms, rain and snow, to the use of vacuum cleaning equipment. With the advancement of aircraft and space technology the influence of these systems is again felt in such cases as the motion of rockets, missiles and aircraft in flight, the behavior of liquid droplets or metallic particles …
The Verification And Use Of A Hot-Wire Anemometer In Turbulence Measurements, Charles Young Warner
The Verification And Use Of A Hot-Wire Anemometer In Turbulence Measurements, Charles Young Warner
Theses and Dissertations
One very important part of research is the development of effective, reliable instruments. The measurement of turbulence in flow fields is a complex research problem. It depends heavily upon the hot-wire anemometer. This thesis describes the evaluation and use of a constant- current hot-wire anemometer, and presents the equations governing its use for turbulence measurements. The thesis first enumerates and explains some of the important parameters of turbulent flows, providing the basis for the discussion of their measurement which follows. The cooling of a heated wire in forced convection and a typical anemometer circuit are discussed. Derivations of the instrument …
