Summary:

Convective heat transfer coefficients were determined for thermocouple junctions oriented parallel to the gas flow for Reynolds numbers (based on wire diameter) from 163 to 17,500. Chromel-alumel wires of 0.013-0.051 inches diameter were tested in air and products of natural gas combustion at temperatures of 60, 500, and 1000 F. Transient response was used to determine the heat transfer coefficient, and all data were corrected for variation of metal specific heat and radiant heat transfer. The affect on apparent heat transfer coefficient was determined for variations in junction weld-bead size, junction length, and wire separation.An empirical equation has been derived relating Nusselt number and Reynolds number that fits 92% of the test data within ± 10%
