Краткое описание

Gas-liquid two-phase flow is a typical complex system with intrinsic spatiotemporal fluctuation in phase distribution, pressure drop, heat transfer, and so on, being an important subject left behind after extensive research on two-phase flow dynamics. Previously developed modeling is not appropriate in application to CHF problems at low quality and/or in downward flow. This is mainly because conventional modeling, including two-fluid modeling, is based on the continuous flow hypothesis. The proposed model, represented by the discrete bubble model, consists of a void propagation equation as a global rule and only a limited number of mechanical and geometrical relationships as local rules, i.e., a wake effect, gas compressibility, and a phase redistribution mechanism. Neglecting detailed mechanisms of two-phase flow, the spatiotemporal fluctuations in void fraction and pressure drop are numerically realized within the framework of the pattern dynamics approach.
