Resumo

Experimental heat transfer and fluid friction characteristics are presented for an impressed plate surface suitable for incorporation in compact recuperative heat exchangers. Two different arrangements having surface/volume ratios of 443 ft.2/ft.3 and 765 ft.2/ft.3 have been tested. Comparisons are made between this and other surfaces on the bases of minimum area and minimum volume for fixed pumping power. It is concluded thet this new primary surface is superior to all existing surfaces of the same degree of compactness, which may be incorporated in compact recuperative heat exchangers. It is claimed that surface/volume ratios as high as 2,000 ft.2/ft.3 ere attainable.
