| Abstract: | The printed circuit heat exchanger (PCHE) is a compact, efficient, safe and reliable heat exchanger type with good application prospects in floating liquefied natural gas platform (FLNG). The research status of PCHE is reviewed, including the classification of PCHE structure, heat transfer characteristics and resistance characteristics. The application status of PCHE in FLNG is summarized. And prospects of PCHE in FLNG is analyzed, including the structure design criteria of PCHE, the influence mechanism of sloshing and measure to defeating sloshing in heat exchangers applied in FLNG. Theoretical basis and research ideas of PCHE designing in sloshing condition are provided. |
