Abstract

Abstract An empirical correlation for the estimation of the droplet entrainment from boiling water pools is under development. The correlation is validated on the basis of experiments, taken from test facilities of different scale, which investigate the effect of several boundary conditions on the droplet entrainment. The calculated values for the droplet entrainment are in good agreement with the experimental data, indicating that relevant influences are considered in the developed correlation with an appropriate quantity. Nevertheless, the application of the correlation on scenarios with flashing pools and non-boiling pools with gas flows through the pool surface have to be investigated in the ongoing validation process. Furthermore, other experiments are needed, which consider pools containing surface-active substances to depict the influence of surface tension on the droplet entrainment.
