“…Naterer [20,21] has correlated transient variations of thermocouple temperature measurements with entropy changes, which can provide useful insight regarding convective instabilities in the flow field. Kendoush [22] performed an experimental study of fluid flow and convective heat transfer in a wake region of a circular disk, using thermistors and a Pitot tube to measure heat transfer and pressure distributions. The results established the local heat transfer coefficient along the diameter in the Reynolds number range between 1.4 · 10 3 and 5 · 10 4 .…”
