Self Sloshing of Thermal-Stratification Interface in LMFBR Hot Plenum

Purpose of this report is to overview thermal hydraulic investigations which were conducted yet. That is to estimate the effects of the elevations of UIS (Upper Internal Structure) discharge and IHX (Intermediate Heat Exchanger) intakes on flow patterns, free surface disturbance and thermal stratification in hot plenum. From the results of the experiments, suitable elevations could be recommended by comparing some thermal hydraulic characteristics and self sloshing of thermal interface called as internal standing wave was observed in certain limited ranges of Richardson number.
