With　the　aim　to　develop　a　generalized　model　for　predicting　the　frost　growth　on　cold　flat　plate,　experiments　were　conducted　in　a　suction-type　open-loop　wind　tunnel　under　variant　frosting　conditions.　Based　on　the　Hayashi　correlation,　a　modified　correlation　of　initial　frost　density　was　developed　by　the　experimental　results.　After　validating　this　proposed　correlation,　dynamic　frosting　characteristics,　such　as　the　frost　thickness,　density,　frost　surface　temperature　and　heat　flux　were　predicted　under　a　wide　range　of　frosting　conditions.　Compared　with　25　groups　of　experimental　results　taken　from　this　paper　or　previous　open　literatures,　the　average　simulating　errors　were　found　to　be　limited　within　+/-　10%.　The　validation　results　indicate　the　proposed　model　is　suitable　to　predict　the　dynamic　heat　and　mass　transfer　process　of　the　frost　growth　under　a　wide　range　of　frosting　conditions.　(C)　2011　Elsevier　Ltd　and　IIR.　All　rights　reserved.
