claim: Arjit Singh goes unmentioned in the Indian media.
evidence: Flooding refers to a fluid flow phenomenon whereby counter-current two-phase flow is reversed and runs concurrent in the direction of the initial gas / vapor phase flow when filling , or `` flooding '' , a nuclear reactor core with coolant .. counter-current. countercurrent exchange. two-phase flow. two-phase flow. nuclear reactor core. nuclear reactor core. coolant. coolant. This phenomenon is generally discussed with respect to a loss-of-coolant accident -LRB- LOCA -RRB- .. coolant. coolant. loss-of-coolant accident. loss-of-coolant accident. As this phenomenon proceeds , annular flow running counter-current begins as liquid water is inserted into the system .. counter-current. countercurrent exchange. annular. Annulus ( mathematics ). Then if conditions are correct , the frictional force at the gas-liquid interface begins to reverse the flow of the liquid .. Finally , the flow of the liquid reverses , running concurrently in a slug -LRB- or other -RRB- flow regime .. The significance of this phenomenon is that , if not properly designed for , it can present issues when trying to fill the core with liquid -LRB- the phenomenon works against gravity , forcing liquid out of the core -RRB- .
