Hot-wire, hot-film and surface hot-film applications in strongly temperature loaded flows

International Congress on Instrumentation in Aerospace Simulation Facilitie, 2003
Hot-wire, hot-film, and surface hot-film measurements in heated or cooled flow are presented. On the basis of an integral heat balance, the ratio of conductive to convective heat loss of a hot-wire, hot-film, or surface hot-film can be formulated in relation to an appropriate Reynolds number. This heat balance is extended to near-wall measurements by a

Hot science at low temperatures

Physics World, 1992
What do superconducting films, the fungal infestation of leaves and storage properties of pharmaceutical creams have in common? The answer is that the characterisation of all of these materials can be assisted by the use of low-temperature scanning electron microscopy (LT SEM).

HOT PRESSING HIGH-TEMPERATURE COMPOUNDS

Powder Metallurgy, 1961
The technique of hot pressing and the factors to be considered in designing suitable equipment are discussed. Examples are quoted of three main classes of materials: (a) unbonded hard materials, (b) materials containing a small amount of a cementing phase or impurity affecting densification, and (c) materials containing an appreciable amount of a ...

Duration of Very Hot Temperatures *

Bulletin of the American Meteorological Society, 1952
Maximum temperatures on very hot days in hot-desert areas are similar in duration and time of occurrence to maximums on cooler days: they occur around three hours after noon, and the temperature (as measured to the nearest whole degree by standard thermometers) remains at the maximum for about two hours.

A constant temperature hot-wire anemometer

Journal of Physics E: Scientific Instruments, 1987
A constant temperature anemometer is described which is designed to operate hot wires with diameters in the range 0.63-5 mu m. A special feature of the design is the use of separate current sources to supply the different halves of the bridge. This feature eliminates the need for dynamic stability compensation, necessary for commercial constant ...

How Hot Is Too Hot?: Some Considerations Regarding Temperature and Performance

International Journal of Sports Physiology and Performance, 2010
The regulation of temperature during exercise is a widely debated topic. Two primary views exist, with one embracing a peripheral approach and the other adopting a more integrative and central explanation of the physiology. Especially in the past 10 years, several investigators have published increasingly elegant interpretations that have moved the ...

Constant-bandwidth constant-temperature hot-wire anemometer

Review of Scientific Instruments, 2007
A 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 ...

Computing indoor temperatures in hot climates

International Journal of Ambient Energy, 1981
SYNOPSIS This paper describes a computational prediction technique for calculating internal temperatures in buildings Research Establishment (BRE) admittance procedure. An application of the technique is shown which compares the measured and calculated temperatures for a test room which is part of a collaborative research project between the General ...
