Plate heat exchanger with diffuser channels
Annotation
A numerical simulation of the heat transfer in plate heat exchangers with diffuser channels with small opening angles was performed with a three-parameter differential turbulence model supplemented by the transport equation for a turbulent heat flux. It is shown that the amount of heat transferred from the “hot” coolant to the “cold” increases as compared that in heat exchangers with channels with a constant cross section due to the heat-transfer enhancement in heat exchangers with diffuser channels.
