| Summary: | The model of equivalent channels for the heat storage nozzle of a regenerative heat exchanger is
considered. Differential heat transfer equations between the heat carrier flow and the surface of
the equivalent channel are given. It is suggested to evaluate the efficiency of heat transfer by the
coefficients of accumulation and heat recovery of ventilation flows. Criteria for calculating the heat
transfer coefficient under laminar and transient modes of gas motion in an equivalent channel is given.
The results of a computational study are presented, which make it possible to evaluate the effects of air
velocity in the channel on the efficiency of a regenerative heat exchanger |
