✦ Synopsis

The heat transfer for turbulent axial flow in close clearance exchangers is analyzed with the aid of the basic surface renewal and penetration principle. This analysis essentially involves two mechanisms of renewal; that is, renewal associated with the periodic scraping action of the blades, and renewal induced by axial turbulence. This analysis indicates that the heat transfer process for close clearance exchangers is influenced by both scraping action and axial turbulence for values of r/t between 0.2 and 50.
