This course deals with various aspects of flow and heat transfer phenomena in multiphase systems, mostly focused on the gas-liquid flow. Basic flow patterns and their background physics will be studied. Also, the conservation equations, analytical models and the experimental results are going to be introduced. As well as the adiabatic cases, the fundamentals on the boiling and the condensation phenomena will be discussed. Besides, recent progress in the multiphase flow research will be briefly introduced.

The students taking this course are assumed to have taken the elementary courses on fluid mechanics, thermodynamics and heat transfer, and are required to participate in the class discussions actively. The course will be taught in English.
Short tests will be given at the end of every lecture.
