Hm. Yeh et Cd. Ho, The improvement of performance in parallel-plate heat exchangers by inserting in parallel an impermeable sheet for double-pass operations, CHEM ENG CO, 183, 2000, pp. 39-48
Considerable improvement of heat transfer in flat-plate heat exchangers is
obtainable by inserting in parallel an impermeable, resistless sheet to div
ide an open duct into two channels for double-flow operations. The effect o
f impermeable-sheet location on the enhancement of transfer efficiency as w
ell as on the increment of power consumption, has been discussion.
