Abstract
A new approach has been proposed to calculate heat transfer coefficient for refrigerants boiling inside tubes. The principal idea underlying the method proposed is an assumption that taking into account phase slip will allow showing various flow patterns and heat exchange for diverse liquids and different parameters under wide-ranging conditions.
