Abstract
A new correlation for frost density prediction is developed based on the experimental database found in the literature. A careful recognition of the main dimensionless groups was performed. The main dimensionless groups were considered in the development of the new empirical model. The experimental database cover flat surfaces with surface temperature range from -20.7°C to -5°C and air temperature range from 13.4°C to 23.4°C. Frost density literature models were also compared with the experimental database. The new correlation best predicted the database with a mean absolute error of 18.9 %.
