A remark on the flash temperature theory
International Communications in Heat and Mass Transfer, 1997The classical solution of the temperature development in a sliding solid pair treats the thermal conductivity as a non-variant quantity that is not affected by temperature elevation. This may introduce an erroneous estimate of the temperature distribution in the contacting pair.

An interpolation formula for flash temperatures
Wear, 1991Abstract A rule is proposed for estimating the surface temperature rise in a single body due to a moving heat source on its surface, by combining the estimates for slow and fast heat sources. Comparisons with other rules are given.

Low temperature flash vaporization for desalination
Desalination, 2005The feasibility of desalination by low pressure vaporization of seawater at temperatures between 26°C and 32°C was demonstrated in a pilot plant. The plant operated at vacuum pressures between 1.3 KPa and 2.3 KPa. The saline water was sprayed into the vaporizer as fine droplets using a swirl nozzle and evaporated at the low pressure.

Body temperatures during menopausal hot flashes
Journal of Applied Physiology, 1975Body temperatures during hot flashes were measured in a menopausal woman. Internal temperatures fell after each flash; lowest: rectal, 35.6 degrees C; vaginal, 35.6 degrees C; tympanic, 35.2 degrees C. Where sweating occurred, the skin temperature fell during the flash and rose after it.

Initial Temperature Evaluation for Flash Temperature Index of Gear Tooth
Journal of Tribology, 1995In the AGMA standard for the scoring resistance evaluation of gears, flash temperature is used as an index indicating the risk of scoring. The flash temperature is expressed as the sum of flash rise of temperature and initial temperature. In this research, the initial temperatures are measured for various gear sets in running by thermocouples which are

Temperature dependence of the flash duration of the firefly Luciola praeusta
Photochemical & Photobiological Sciences, 2014Firefly flashing has attracted the attention of both poets and scientists for over a century. Here we study the effect of temperature on the flash duration of the Indian species of the firefly Luciola praeusta Kiesenwetter 1874 (Coleoptera: Lampyridae: Luciolinae). Recording in vivo time-resolved spectra of specimens of this species of firefly over the

Estimation of Flash Temperatures in Dry Sliding
Proceedings of the Institution of Mechanical Engineers, Part C: Mechanical Engineering Science, 1984The paper develops expressions for the flash temperatures experienced by contacting surface asperities during dry sliding. The analysis is based on the heat transfer equations of the Jaeger—Archard theory but additional terms are introduced to allow for the effects of junction growth and cold work in plastic conjunctions.

Mapping temperatures and temperature gradients during flash heating in a diamond-anvil cell
Review of Scientific Instruments, 2013Here, we couple two-dimensional, 4-color multi-wavelength imaging radiometry with laser flash heating to determine temperature profiles and melting temperatures under high pressures in a diamond-anvil cell. This technique combines the attributes of flash heating (e.g., minimal chemical reactions, thermal runaway, and sample instability), with those of ...

An analysis of temperature distribution of heat flash
International Conference on Optoelectronic Science and Engineering '90, 1990This paper is to apply the infrared thermography and image processing technique to improve the measured precision for heat flash. In the laboratory and the shooting range,pass through more than hundred times projectile tests,the temperature distribution of heat flash was monited by infrared thermography using the gray thermogram, color thermogram and ...

LASER FLASH PHOTOLYSIS OF RHODOPSIN AT ROOM TEMPERATURE
Photochemistry and Photobiology, 1977Abstract. Nanosecond flash photolysis of rhodopsin with 530 or 353 nm light produces an initial transient absorption spectrum with peaks at ˜57O and ˜420nm, and a subsequent transient species with a maximum absorption at 480 nm. These results are interpreted as the initial formation of prelumi‐rhodopsin (570 nm) followed by its conversion to ...
