Two-phase flow is one of the most common flows in nature as well as in industrial applications. It covers gas-solid, liquid-liquid, solid-liquid and gas-liquid flows. As an example, gas-liquid flow, which also includes the whole subject of boiling and condensation, is a topic of the utmost importance and exists in a wide range of industrial applications including evaporators, boilers, distillation towers, chemical reactors, condensers, oil pipelines, nuclear reactors, etc. In spite of the many efforts that have been made by the scientific community in terms of both economical and human resources, advancements in the knowledge of two-phase fluid dynamics have been relatively limited, so that very often two-phase phenomena cannot be adequately predicted or controlled.
This course deals with some recent advancements in two-phase flow modeling, with emphasis on gas-liquid and liquid-liquid systems. The topics of the lectures will cover the fundamentals of multiphase flows, closure problems applied to the mathematical modeling of the different flow patterns, pressure gradient and singular pressure drops in pipelines, boiling and condensation phenomena, experimental techniques for two-phase flow diagnostics. Emphasis will be given to topics which are subject of current research, such as liquid-liquid flows, flow visualization techniques, pressure drops across pipe fittings, turbulent dispersed flows.
The course will be complemented by a workshop, with the aim to provide a fertile environment for discussions, where participants to the course as well as academics and industry experts from both Engineering and Physics could present their recent results.
The course is addressed to Ph.D. students and postdoctoral researchers in mechanical, nuclear and chemical engineering, applied mathematics and physics, who are interested in broadening their knowledge in the area of two-phase flow, and to senior scientists and engineers from relevant industries or institutions.
