Abstract:
The goal of this paper is to investigate thermal and fluid flow processes in a air/water perforated plate heat exchanger. The experimental investigation was carried out over a single perforated plate which was installed in an experimental chamber and heated by hot water. A fan with variable flow was connected to the experimental chamber, and the flow rates were varied from 100 up to 360 m3/h. The thermocouples were attached to the surface of the perforated plate along upwind and downwind side, as well as at the inlet and outlet of the chamber. During each experiment, the readings of thermocouples were recorded alongside with air and water volume flow and temperatures of water at the inlet and outlet of the chamber. On the basis of the experimental results equations for heat transfer and pressure drop were established. On the end, a comparison was done with other authors.

Key words:
perforated plate, experimental research, heat transfer, pressure drop

Thematic field:
