An experimental study has been performed to clarify the pressure drop characteristics of a newly proposed hybrid type of gas-to-gas heat exchanger, which has heat transfer surfaces made up of porous metal plates and/or finned walls. As a first step to conduct detained investigations on that subject, a series of experiments have been carried out using a three-layered type of gas-to-gas heat exchanger under an isothermal flow condition. From the experiments, fundamental pressure drop characteristics have been clarified on the system with zigzag fin walls along with those on the system with bare walls. Further correspondence between the pressure drop characteristics and the previously measured temperature distributions in the heat exchanger and the total heat recovery rate is also shown.
