Abstract
This work describes a quantitative experiment that evaluates heat transfer during the cooling of a steel cylinder employing temperature sensors. An equation considering convection and radiation heat transfer in a solid is deduced form the energy balance equation and a convective heat transfer coefficient, also known as film coefficient, is determined for each time interval. Experimental results are compared with theoretical values of this parameter, calculated with available correlations in the literature. This work shows the importance of considering together the mechanisms of convection and radiation in ambient air cooling. It also provides goods results with the use of low cost equipment and a test of easy execution.
