Abstract: The temperature measurement system includes a thermocouple probe, a non-transitory computer-readable storage medium storing processor-executable instructions, and a processor. The processor-executable instructions are configured to enable to processor to form a model of the thermocouple probe, perform several computational fluid dynamic (CFD) analyses of the thermocouple probe using a predetermined Reynolds number, output a first temperature (T1CFD) and a second temperature (T2CFD) at the junctions for each simulation, apply a linear regression between the T1CFD and the T2CFD, output a slope from the linear regression, and output a corrected gas temperature with at least one algorithm.
