The Hot-Wire Anemometer in Supersonic Flow
Journal of the Aeronautical Sciences, 1950The hot-wire anemometer has proved to be a most valuable tool for turbulence research in the low-speed range. As interest grows in the problem of turbulence at supersonic velocities, it would appear natural to see whether the hot-wire anemometer could not also be used at higher speeds. However, a number of fundamental problems must be solved before the

Hot Wire Anemometer in Liquid Mercury
Review of Scientific Instruments, 1965A hot wire system has been developed which is suitable for operation in liquid mercury at speeds from 1 to 12 cm/sec. The wire was 38 μ diam tungsten with 2.5 μ thick enamel coating, used with 2 A heating current in constant current operation. The Nusselt number was determined experimentally as a function of Péclet number in the range 0<Pé& ...

Abstract : This paper presents the need for an accurate low wind speed measuring system for the White Sands Missile Range Wind Instrument Test Facility. It describes a device that has been installed in the facility and which operates on the principle of periodic eddy shedding on the down-wind side of a cylinder.

Constant-bandwidth constant-temperature hot-wire anemometer
Review of Scientific Instruments, 2007A constant-temperature anemometer (CTA) enables the measurement of fast-changing velocity fluctuations. In the classical solution of CTA, the transmission band is a function of flow velocity. This is a minor drawback when the mean flow velocity does not significantly change, though it might lead to dynamic errors when flow velocity varies over a ...

Low speed calibration of hot-wire anemometers
Flow Measurement and Instrumentation, 2007Abstract A device for calibration of hot-wire anemometers at low velocities is described. The calibration technique is based on moving hot-wire probes in stagnant air. The device is relatively small, highly mobile and consists of a horizontal swing arm rotated by a DC motor.
