โœฆ Synopsis

A new correctional calculation method is proposed for measurements of temperature profiles in flames with a thermocouple. This method includes an iterative procedure of correcting a temperature prof'de with respect to conductive and radiative heat losses.

Experiments were performed on hydrogen-air and town gas-air flames. Three different sized thermocouples (0.1, 0.3 and 0.5 mm in alia.) were introduced and the temperature prof'fles were measured. The real temperature prof'fles were computed according to those data. The corrected profiles were in agreement with each other.

Furthermore, the accuracy of this correctional method is discussed by taking into consideration the influence of several parameters on heat transfer.

A thermocouple device for the measurement of the surface temperature of a liquid metal when non-uniform and/or rapidly changing temperatures exist in the liquid is described. A mathematical analysis of its principle is made from which the accuracy of its measurements are calculated and plotted.
