Previous work on the existence and influence of sliding bubbles within the two-phase flow in tube bundles is reviewed. New experimental evidence based on the heating and cooling of a single tube situated in the bubbly flow within a tube bundle is presented. These sliding bubbles from a hitherto unrecognised flow regime between nucleate boiling and convective evaporation in the bundle. This sliding bubble regime leads to a new approach to the analysis of heat transfer in tube bundles. The effects of flow and geometrical parameters on the shell-side heat transfer coefficient are determined using a tube by tube computer analysis based on this approach.
