Outline of Final Research Achievements

To develop the new two-phase flow prediction method which contributes improvement of a ship drag reduction technology based on air lubrication method, experimental and analytical studies on two-phase flow structure were performed. First, database on local two-phase flow parameters such as void fraction, interfacial velocity, interfacial area concentration and bubble diameter in a rectangular channel, which simulates the external two-phase flow, was constructed first, and influential factors characterizing the two-phase flow structure were evaluated based on the database. Prediction methods for two-phase flow structure in velocity boundary layer, which includes void fraction, interfacial area concentration and wall frictional drag were newly developed and the applicability of them were evaluated by comparing with the available experimental data.
