The fluid mechanics and heat transfer in two-phase flow has always been a challenging matter. The consequences of the interaction between the liquid and the vapour phases provide the reasons for the application in a wide field of fluid systems. In the present work, the characterization of the liquid film distribution in horizontal two-phase annular flow has been investigated in order to understand its effect on the pressure drop and the heat transfer coefficient. This topic may be very important in the design of heat exchangers involved by two-phase flows with significant liquid film stratification.

Filippo Cataldo began the studies in mechanical engineering at the University of Naples "Federico II" on September 2007. He got the Master of Arts in Mechanical Engineering at the same university on September 2012. Afterwards, he received the PhD on April 2015 about Two-phase Flow and continues the research on the topic ever since.
