WebThermal-hydraulic analysis of flow blockage. In plate-type fuel reactors, rectangular channels are spaced apart from each other, and there is no mixing between them. Therefore, when the heat transfer in a coolant channel of a certain fuel elements deteriorates, thermal and hydraulic conditions of the poor channel may be worse … Web3.3 Plug-flow reactors. Alternatively enzyme loaded beads could be packed into a porous bed and reactants could be flowed through this bed. This type of reactor is called a plug-flow reactor.
