报告题目：Model development for two-phase flow

报告简介：The two-phase flow thermo-fluid dynamics is a complicated subject due to the existence of moving and deformable interface and its interactions with the two phases. Professor Hibiki gave his first seminar to students at Xi'an Jiaotong University on December2, 2019. The first seminar was focused on the Fundamentals of Two-phase Flow. This is the second seminar of the Advanced Two-phase Flow Modeling seminar series. The second seminar will be focused on the modeling of two-phase flow regime transition criteria. The flow regime identification and prediction are essential in two-phase flow research because the interfacial structure characterizes two-phase flows. The constitutive equations used in computational codes heavily depend on the flow regime. In the seminar, Professor Hibiki will explain the modeling tips and demonstrate the flow regime transition criteria' derivation. Students will learn how to approach modeling of thermal-fluid phenomena and accumulate the knowledge of state-of-the-art flow regime transition criteria in various flow conditions and geometries.
