Question

RRB Paper · Accepted Answer

In the regenerator-type heat exchanger, heat transfer takes place by the flow of hot and cold fluids alternately over a surface. Regenerators are compact heat exchangers in which heat is alternately stored and removed using a heat storage matrix. During the hot period, heat is transferred from the hot fluid and is stored in the packing of the regenerator. In the subsequent cold period, this heat is regenerated and is transferred to the cold fluid passing through the exchanger.

In regenerator type heat exchanger, heat transfer takes place by

Direct mixing of hot and cold fluids

A complete separation between hot and cold fluids

Flow of hot and cold fluids alternately over a surface

Generation of heat again and again

The correct answer is `No. 3: Flow of hot and cold fluids alternately over a surface`
