Experiments in Fluids, 1984
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 ...

Phenomena at hot-wire electrodes
Fresenius' Journal of Analytical Chemistry, 2000An overview is given describing phenomena at heated microelectrodes where matter and heat energy are simultaneously emitted into the solution. With controlled electric heating, virtual "quiescent" periods as well as ones with constant streaming conditions are found that depend on the heating time.

Journal of Scientific Instruments, 1929
Instruments based on the convective cooling of an electrically heated wire, for giving the distribution of velocity across a liquid (a) flowing in a cylindrical tube, (b) flowing in the annular space between two concentric cylinders, one rotating and the other at rest, are described.

Journal of Physics E: Scientific Instruments, 1982
The region of validity of conventional hot-wire signal analysis and the accuracy of the values of the flow parameters calculated using this analysis have been investigated and an alternative analysis of hot-wire signals is proposed. Furthermore, the loss of accuracy is determined in the values obtained for the flow parameters when the cooling ...

Bidirectional hot-wire anemometer
Review of Scientific Instruments, 1982A simple hot-wire anemometer based device has been designed and developed which is capable of measuring flow reversals. The instrument has a useful range of 0 to ±150 cm/s.

Hot-wire anemometry is still a major research tool for the study of turbulent flow. Following the publication of the general book on Hot-wire Anemometry by H H Bruun in 1995 there has been a need for an up-to-date description of some of the more advanced hot-wire anemometry methods.

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 ...
