MEASUREMENT OF LOCAL WALL TEMPERATURE AND HEAT FLUX USING THE TWO-THERMOCOUPLE METHOD FOR A HEAT TRANSFER TUBE

Measurement of local wall temperature and heat flux using the two-thermocouple method for a heat transfer tube

The two-thermocouple method was investigated experimentally to evaluate its accuracy for the measurement of local wall temperature and heat flux on a heat transfer tube with an electric heater rod installed in an annulus channel.This work revealed that a thermocouple flush-mounted in a surface groove serves as a good reference method for the accura
