The　liquid　evaporation　from　nanoscale　pores　has　attracted　much　attention　from　researchers　due　to　its　importance　in　water　treatment　and　device　cooling　related　applications.　It　is　crucial　to　investigate　the　receded　liquid　case　as　the　vapour　flow　resistance　in　a　nanopore　has　high　impacts　on　the　evaporation　rate.　This　paper　proposed　a　semi-empirical　analysis　on　nanoporous　evaporation　with　a　receded　liquid　surface　under　the　influence　of　the　Knudsen　number.　The　vapour　flow　dynamics　in　a　nanopore　was　examined　considering　the　multiple　reflections　of　vapour　molecules.　We　calculated　the　value　of　pore　transmissivity　based　on　transitional　gas　flow　correlation　which　incorporated　the　effect　of　the　Knudsen　number.　Direct　simulation　Monte　Carlo　method　was　employed　to　provide　validation　for　the　present　model.　The　vapour　density　jump　near　the　liquid　surface　and　the　pressure　ratio　between　the　far　field　and　saturation　value　were　predicted　by　our　model　with　good　precision.　It　was　shown　that　the　vapour　flow　resistance　in　the　nanopore　accounted　for　more　than　90　%　of　the　total　resistance　in　present　cases.　With　increasing　Knudsen　number,　the　pressure　ratio　gradually　drops　and　reaches　an　asymptotic　level.　This　suggested　a　relatively　higher　evaporation　resistance　in　free　molecular　regimes.　The　present　work　revealed　the　importance　of　the　Knudsen　number　in　nanoporous　evaporation　with　receded　liquids,　providing　insights　into　the　governing　factors　under　various　Knudsen　regimes.
