The heat transfer and flow friction characteristics of a number of parallel plate surfaces with round or slotted perforations are presented. Their performance is compared to the parallel nonperforated plate as a standard and is shown to be very promising in terms of reducing the free area of volume of gas turbine regenerators. Sound and vibration phenomena were observed and recorded. To gain an understanding of the flow behavior over the perforations, a scaled-up flow visualization study was performed.
