Storage systems

Consider the operation of the sensible heat storage system shown schematically in Figure 7.1. The system consists of a large liquid bath of mass M and specific heat C placed in an insulated vessel. Hot gas enters the system through one port, is cooled while flowing through a heat exchanger immersed in the bath, and is eventually discharged into the atmosphere. Gradually, the bath temperature T as well as the gas outlet temperature Tout rises, approaching the hot gas inlet temperature T~.
