Realistic problems involving thermal conductivity

Modelling and measurements of heat transfer coefficient in classroom experiments

“…Problems involving heat transfer are rarely included in experimental exercises in secondary schools because of their complexity, especially of the boundary conditions. Only a few studies have been published on this subject [1][2][3][4]. In [1], the thermal conductivity of a brick was determined, but simplified boundary conditions were used, neglecting convection.…”

“…thermal contact existed between the heater and the investigated sample (asphalt) to determine its thermal conductivity. In [4], a problem related to the heat transfer through windows, including thermal conductance, convection, and radiation, was investigated. However, the article is pedagogical in demonstrating ways to approach the complex problem of heat transfer through a solid plate surrounded by a low-viscosity fluid without proposing a setup and exercises suitable for a classroom.…”

An experiment in heat conduction using hollow cylinders

“…Heat conduction in solids has been studied extensively for many years. Díaz-Aguilera [4] studied the heat conduction in one-dimensional solids, Ràfois and Ortín [5] presented an experimental realization of the problem of heat conduction along a one-dimensional metallic rod with Newtonian losses and Bee et al [6] analyzed realistic problems involving thermal conductivity. Transient heat conduction has been experimentally analyzed by Brody et al [7] using an optical set-up with M. Ortuño, A. Márquez, S. Gallego, C. Neipp and A. Beléndez, "An experiment in heat conduction using hollow cylinders", European Journal of Physics, Vol.…”
