چکیده انگلیسی
In this paper, the developed algorithm was described, which can discriminate the local phase temperature in the two-phase flow measured by a self-designed micro-thermocouple with an outer diameter of 12.7 μm. The algorithm used to calculate the temperature of each phase was based on the response time of the micro-thermocouple and the exponential regression method. This algorithm was verified by conducting experiments with an optical chopper and a laser. It was shown that the more accurate temperatures were measured, when the newly proposed algorithm was used. Moreover, this algorithm was applied to the measurement of the liquid temperature in subcooled flow boiling. The measured liquid temperatures in subcooled flow boiling were used to assess the capability of the CFX-4.2 code, additionally.
