Purpose of the course: Multiphase flow and the heat transfer associated with these flows are gaining increasing importance in industry. The reason for this is that higher heat transfer coefficients are obtained in multi-phase flows compared to single-phase flows and it allows applications with high heat flux. Multiphase flows are widely used in various industrial systems such as steam generators, cooling systems, nuclear reactors, chemical production units and refineries. By introducing the flow regimes that occur in multiphase flows, the models developed for each flow model will be examined and the experimental and numerical solution approaches will be analyzed.
