文摘

Surface energy can influence frost density on hydrophilic and hydrophobic surfaces. A new semi-empirical correlation for the prediction of frost density is proposed. New correlation predicts more than 93% of the data (n = 522) to within ±20%. Correlation is proposed for use on surfaces with contact angles 45° < θ < 160°. Larger frost density values are predicted on hydrophilic surfaces.
