Influence of thermocouple angles and wire distance on temperature measurement

1D numerical correction for temperature measurement with inclined thermocouples

“…Experiment that measures the Hencken H 2 /air diffusion flame with the Omega S-type P10R-010 and P10R-020 thermocouples is used to verify the application accuracy of the correlation in the 1D numerical program. Table 8 shows the real gas parameters at the measurement location [12]. And the emissivity correlations of the two thermocouples are shown in Eqs.…”

“…9 show the comparison between the experimental temperature and the 1D simulated temperature under 7 different pitch angles. All experimental data come from Li et al [12]. The 1D numerical program generates a bead temperature error between -11 K and 24 K, with the larger errors for smaller pitch angles.…”
