Spatial Temperature

The temperature distribution in gaseous SF6 and SF6-inert gas samples under irradiation with cw CO2 laser measured by a thermocouple technique is confronted with the results of a computational procedure neglecting heat convection. The results are helpful in understanding the effect of the inert gas on the distribution of temperature and the size of the reacting hot volume in the cw laser-photosensitized chemical reactions.

Spatial Temperature

The space-time dependence of temperature is analysed in the case of out of doors fire. It is assumed that the fire is caused by a series of point heat sources. The analytical expression of temperature has been found and the line of maximum temperatures, depending on the wind velocity, has been investigated.
