The design of total temperature probes for accurate measurements in hot, high-speed flows remains a topic of great interest in a number of engineering areas, despite a broad and deep prior literature on the subject. Prediction of error sources from convection, conduction and radiation is still an area of concern. For hot-flow conditions, the probe is normally mounted in a cooled support, leading to substantial axial conduction. Also, radiation plays a very important role in most hot, high-speed conditions. One can apply detailed computational methods for simultaneous convection, conduction and radiation heat transfer, but such approaches are not suitable for rapid, routine design studies. So, there is still a place for approximate analytic methods, and that is the subject of this paper.
