“…[8]. In brief, they can be widely used in measuring temperature [372][373][374][375], in measuring generated heat from chemical reactions [376], in gas sensing [377][378][379][380][381] and biological sensing [376,382]and be incorporated into other sensing systems. In such sensors, a variation in the generated voltages induced due to the Seebeck effect in TE materials are used to assess the sensor performance [383].…”

Transition metal oxides (TMOs) are a fascinating class of materials due to their wide ranging electronic, chemical and mechanical properties. Additionally, they are gaining increasing attention for their thermoelectric (TE) properties due to their high temperature stability, tunable electronic and phonon transport properties and well established synthesis techniques. In this article, we review TE TMOs at cryogenic, ambient and high temperatures. An overview of strategies used for morphological, composting and stoichiometric tuning of their key TE parameters is presented. This article also provides an outlook on the current and future prospects of implementing TMOs for a wide range of TE applications.

“…Heat flux measurements for convective heat transfer are widely used in applications with harsh thermal environments including high enthalpy plasmas, high pressure arc heaters, high power pulsed lasers and structural thermal tests [21][22][23][24][25][26][27][28][29][30][31][32]. However, heat flux distribution measurements in high pressure, high temperature and hypersonic flows are still extremely difficult.…”

Heat flux measurements are widely used in thermal environment analyses. The Gardon gauge is an excellent heat flux sensor with a wide measurement range and long lifespan in harsh environments. However, the Gardon gauge is usually calibrated for radiation heat transfer and is not good for convective heat transfer. This paper introduces a method to measure heat flux for convective heat transfer using the Gardon gauge by relating the measurement sensitivity for convection to that for radiation. The heat flux and convective heat-transfer coefficient can then be simultaneously determined by the standard thermo-electromotive voltage output of the Gardon gauge. The method was demonstrated for convective heat-transfer coefficient ranging from 200 to 3000 W/(m 2 K). The analysis illustrates that the measurement sensitivity for convection decreases with increasing convective heat-transfer coefficient. A correction is necessary especially for higher convective heat-transfer coefficient. The corrected convective heat-transfer coefficients and heat fluxes agree well with the actual values. The relative uncertainty in heat flux is within 0.64%. The method not only greatly improves the measurement accuracy of the Gardon gauge for convection applications, but also provides a reference for evaluating convective heat transfer coefficients in convection environments.

“…There are designs with an additional resistance thermometer at the front face to measure absolute surface temperature and new developments with more sophisticated analysis of the heat conduction through the thin layer. 25 Since these sensors are not measuring on a high catalytic surface, they are not considered further throughout this work.…”

This article reviews heat flux measurement devices for high enthalpy flows as used in plasma wind tunnel facilities. Only heat flux gages measuring heat flux on cold copper surfaces are considered. The steady state water-cooled calorimeter, the Gardon gage sensor, slug calorimetry and swept nullpoint calorimetry are described. Based on published data and sensor heritage the various designs in Europe and the US are reviewed and analyzed. The paper ends with some remarks on comparability testing in different facilities.
