Aero-thermal analysis of shielded fine wire thermocouple probes

Research output: Contribution to journal › Article › peer-review

Abstract

Thermocouple probes for high accuracy gas temperature measurements require specific designs optimized for the application of interest and precise characterization of the uncertainty. In the present investigation a numerical procedure is proposed that outperforms previous experimental approaches to analyze the thermocouple response and the different sources of temperature error. The results presented from conjugate heat transfer simulations on different shielded thermocouples, provide information of the influence of the design parameters on the different error sources. These outcomes should help experimentalists to better design future instrumentation.
