Abstracts
Accurate prediction of size, shape and velocity of a bubble rising through a liquid pool is very important for
predicting the particulate removal efficiency in pool scrubbing, for designing engineering safety features to prepare for
severe accidents in nuclear power plants, and for predicting the emission of fission products from MCCI (molten core–
concrete interaction) process during severe accidents. In this review article, previous studies on the determination of
the size, shape and rising velocity of a bubble in liquid are reviewed. Various theoretical and parameterization
formulas calculating the bubble size, shape and velocity from physical properties of liquid and gas flowrate are
compared. Recent studies tend to suggest simple parameterizations that can easily determine the bubble shape and
rising velocity without iteration, whereas iteration has to be performed to determine the bubble shape and velocity in
old theories. The recent parameterizations show good agreement with measured data obtained from experiments
conducted using different liquid materials with very diverse physical properties, proving themselves to be very useful
tools for researchers in related fields.
