A History of Gas-Liquid Two

Phase Flow Research and the Related Technology (2nd Report)

Abstract

The progress of two-phase research is divided into four stages. These periods are 1948-1959, 1960-1970, 1971-1979, and 1980-1988. In this 2nd Report the characteristics of each stages are summerized briefly. Also researches on water circulation in boilers and the relative velocity between gas and liquid in the pre-historical period before 1947 are described in relation to the researches on two-phase flow in the first period. The development and characteristics of researchs in the second period are discussed.
