Gas-liquid flows occur in various industrial applications, such as power generation, refrigeration, oil & gas production, and thermal management of future electronic devices. In this course, one-dimensional models of two-phase flow with and without phase change will be introduced. Methods of pressure drop prediction for adiabatic gas-liquid flow as well as flow boiling will be discussed. Special methods for pressure drop modeling of two-phase flow in miniature channels will also be introduced.
INTENDED AUDIENCE: Postgraduate and final year undergraduate students in mechanical and chemical engineering; engineers working in the industry and R&D labs.PREREQUISITES: Undergraduate level background (first course) in fluid mechanics, thermodynamics and heat transfer.
