Free convection heat transfer from a vertical cylindrical tube bundle

Free convection heat transfer from verti-tube bundles is encountered in nuclear spent fuel storage pools, energy storage devices, room heaters, vertical thermosyphons and other heat transfer equipment. The first of these situations is of much importance because of the strict regulatory laws. In the work reported here, free convection heat transfer was studied experimentally from a tube bundle under the boundary conditions of the second kind. The results obtained were compared with the closest geometrically similar situation available in the literature. (author)
