Experimental study of natural convection heat transfer in a vertical internally finned tube

This paper present an experimental study of a vertical internally finned tube subjected to natural convection heat transfer. All the main parameters that can significantly influence the heat transfer performance of finned tube have been examined. An experimental set-up was designed to study the heat...
