A History of Gas-liquid Two-phase

Flow Research and the Related Technology (6th Report)

Abstract

The progress of the two-phase flow research can be divided into four stages. These periods are 1948-1959, 1960-1970, 1971-1979, and 1980-1990. In this 6th Report, the initiation of research into flow oscillation in the natural circulation loop of boilers and boiling water reactors in the first period (1948-1959) is introduced. Also described is the progress of research on flow instability, that is, flow oscillation, in circulation loops conducted for the development of boiling water reactors at the initial stages of the second period.
