A hot-wire pyrometer for measuring gas temperatures with a high sensitivity has been developed. The method can easily be extended to measurements of surface temperature. The principal elements of a hot-wire pyrometer are a fine wire inserted into the gas and a photomultiplier for measuring the radiation emitted from it.

Abstract This book is a comprehensive, easy-to-access reference book for students, engineers and researchers engaged in the practical use of any aspect of 'hot wire' anemometry (HWA). The book introduces the logical framework for a computer based HWA system and identifies the individual steps in the complete experimental procedure ...

A study on the static calibration of a hot wire
IEEE Transactions on Instrumentation and Measurement, 1981It is shown that the method of nonlinear regression is more suitable in the determination of the parameters of the static calibration of a hot wire. The method has a distinct advantage that the exponent n is independent of flow velocity.

Hot-wire synthesis of Si nanoparticles
Thin Solid Films, 2008Abstract The viability of producing silicon nanoparticles using the HWCVD process is investigated. A system is assembled and particles are produced from silane at pressures between 0.2 and 48 mbar, with hydrogen dilutions of 0–80%, at a total flow rate of 50 sccm and with a tungsten filament maintained at 1650 °C.

A flying hot-wire arrangement has been developed for the measurement of the velocity characteristics of the flow around airfoils, and particularly in regions where negative values of instantaneous velocity occur. The mechanism and signal processing system are described and appraised by comparing stationary and flying wire measurements obtained in the ...

In response to the 'digital divide', national and local governments in the UK, the US and Australia have embarked on various initiatives designed to promote the use of computer networks in low-income communities. These initiatives involve common models of self-help and mutual obligation; the pattern is one where government provides seed funding to ...

A compact hot-wire cutting system
The British Journal of Radiology, 1982Irregularly-shaped shielding blocks are required in several kinds of radiotherapy treatments, and a low-melting point alloy is often used as blocking material. Expanded polystyrene is then the appropriate moulding material, as it can be cut by means of a simple hot wire, using the patient's radiograph as the cutting template.
