Ishii—Zuber

A reduced velocity (Boure, 1966 Ishii and Zuber, 1970) involving the flow rate-versus-heating power ratio or its reciprocal [phase change number in Ishii and Zuber (1970)]. This group includes the specific volume ratio in Boure (1966) and in Ishii and Zuber (1970). 

Some other dimensionless groups are also used individually to account for other minor effects. The basic concepts of the principal dimensionless groups used by Boure (1966) and by Ishii and Zuber (1970) were compared by Boure et al.

Review of the literature was given by Boure et al. (1973), in which the physical mechanisms and mathematical models in use up to that time are discussed. The report has a summary of the computer codes that had been applied to the problem in the frequency and time domains. Saha (1974), Ishii (1976), Saha et al. (1976), and Saha and Zuber (1978) provided initial investigations into effects of thermal nonequilibrium between the liquid and vapor phases. Lahey and Drew (1980) discussed instability issues associated with LWRs.
