# Dynamics of Two-Phase Flows

## 描述

These proceedings of the third Japan-U.S. Seminar on Two-Phase Flow Dynamics, held in Ohtsu, Japan in July 1988, feature a broad review of the status of research relating to two-phase flow dynamics both with and without phase change. The papers cover fundamental equations and closure laws, flow regime modeling and dynamics, phase separation and distribution phenomena, wave and shock phenomena and critical flows, and forced convective and post-dryout heat transfer.
