Resfriamento de um cilindro de aço: Estudo experimental da convecção e radiação do calor

Abstract

This work describes a quantitative experiment to evaluate the heat transfer during the cooling of a steel cylinder and compare the experimental results with predicted values in convection and heat radiation models. In addition to performing the tests, the student is required to prepare a spreadsheet that details the calculations performed and evaluates the consistency of the results. The experiment was designed to be easily implemented in experimental classes of undergraduate courses; and, for this, we tried to use materials and equipment that make feasible the realization of simple and easy execution tests. The results obtained are satisfactory and provide a quantitative analysis on heat transfer mechanisms involved in a real physical system.
