The fuel coolant interaction (FCI) phenomena are characterized by a configuration that a hot particle/droplet surrounded with vapor film moves in coolant liquid. A drag correlation has not been developed for such a configuration. In this study, based on the basic conservative equations, the drag coefficients between a single hot particle/droplet and the surrounding coolant liquid under laminar and turbulent flow conditions are developed first. The coefficients are expressed as functions of Reynolds number, vapor/liquid viscosity and density ratios and the other two dimensionless numbers newly introduced in this study. The drag coefficients for a multi-particle/droplet system under laminar and turbulent flow conditions are then developed based on the above single hot particle/droplet model and the mixture viscosity concept. The proposed correlations are coupled into the SIMMER-III code and are used to simulate the QUEOS experiment. It is shown that the proposed correlations reasonably improve the agreement of the calculated results with the experimental data.
