A temperature probe using a platinum 'hot-wire' which can be used to measure the local stagnation temperature in a hypersonic boundary layer was designed and tested. The temperature dependence of the wire properties is taken into account which greatly extends the probe's operating range. The primary function of the probe is to measure the temperature profiles in the sublayer. The small wire size (0.0001 inches) and suitable probe design make it possible to make measurements to within 0.003 inches of the wall. (Author).

A temperature probe using a small thermocouple wire with its axis placed normal to an airstream was designed, built and tested. The primary purpose of the probe is to measure the stagnation temperature distribution through a supersonic turbulent boundary layer. The small probe size permits measurements in the laminar sublayer region. The probe's simple geometric shape and design provides simplicity in determining the local gas temperature. Experiments were made to measure the local stagnation temperature of the flow with an accuracy of 5R over a moderate temperature range of 560R to 780R. (Author)

This 1985 book provides a summary of the theory and practice of the hot wire anemometer, an instrument used to measure the speed of fluid flow. Many techniques and uses of this instrument are discussed in detail. The author considers such topics as probe fouling, probe design, and circuit design, as well as the thermodynamics of heated wires and thin films. He also discusses measurements of turbulence, shear flows, vorticity, temperature, combined temperature and velocity, two-phase flows, and compressible flows for measurements in air, water, mercury, blood, glycerine, oil, luminous gases, and polymer solutions. The book concludes with a section on the pulsed wire anemometer and other wake-sensing anemometers. This book assumes a familiarity with basic fluid mechanics. However, mathematical descriptions occur near the end of each chapter thus allowing those with a limited mathematical background to make use of the practical details at the beginning of each chapter.

A workshop on flow visualization and flow measurement techniques was held at Silver Spring, Maryland, on 21 and 22 October 1971 and co-sponsored by the Naval Air Systems Command and the Naval Ordnance Laboratory. The objective of this meeting was to provide a forum for technical discussions on new and improved flow visualization and flow measurement techniques. Discussion of the application of new techniques to flow problems associated with turbo-machinery, aircraft and missiles was included. (Author).
