摘要

This paper begins by reviewing some recent and important mathematical findings in one- and two-dimensional half-space studies for increasing the stability and hence predictive accuracy of both the local and projected heat flux based on time histories of local temperature sensors. Applications involving thin film heat flux gauges, null-point calorimetry and physical experiments benefit from the concepts related and demonstrated in this paper. Next, we investigate heat transfer in nozzle walls subject to a hot gas flow. The prediction of the heat flux near the throat region is often a critical issue. The focus of the present study involves the prediction of the throat surface temperature and heat flux based on interior temperature measurements located at a fixed axial position but at various radial locations,. The key fundamental analytic result of this paper indicates for early times (which depends on the thermal diffusivity) that the heat flux, q"(r;t) strongly dependents on both the temperature (T, °C) and heating rate (^, °C/s) as.
