| Abstract: | The objective of this study is to provide the numerical model for prediction of the
frost growth of the round plate fin for the purpose of using as a round plate fin- tube heat
exchanger (evaporator) under frosting conditions. In this study, numerical model was
considering the frost density change with time, and it showed better agreement with
experimental data of Sahin (1994) than that of the Kim model (2004) and the Jonse and
Parker model (1975). This is because the prediction on the frost height with time was
improved by using the frost thermal conductivity reflecting the void fraction and density of
ice crystal with frost growth. Therefore, the developed numerical model could be used for
frosting performance prediction of the round plate fin-tube heat exchanger. |
