Course plan or Lecture plan

Flow parameters characterizing multiphase flow, such as flow pattern and void fraction, are introduced, and
modeling and basic equations are shown. Furthermore, characteristic flow phenomena such as instability and wave propagation in the multiphase flow are explained in detail.
