An apparatus was designed and carried out on a physical model which was included an air tunnel and a cold cylinder exposed to humid air flow. It was found that the frost layers formed on the front and rear surfaces of the cylinder were thicker than the top surfaces where the flow separation was nearly or wholly initiated. The effects of air flow parameters such as flow Reynolds number, entrained air temperature, absolute air humidity and temperature of cylinder surface on the frost thickness and density formed over the cylinder were studied. In this paper, the dew point temperature of the inlet air was above the freezing point and also the earlier transition time was investigated.
