The objective of this work is to provide a correlation between the heat transfer coefficient and the Nusselt Number with the flow Reynolds number for a truncated cylindrical probe in cross-flow, a configuration that has not previously been well defined. In the experiment, thermally stabilized, dry air was discharged into the test section across a heated probe that was instrumented with thermocouples and exhausted to atmosphere. Experimental data were recorded for several run conditions. A correlation between the probe heat transfer coefficient and the Reynolds number was developed with a calculated uncertainty of 1.24%.
