Abstract

One of the problems relating to frost formation in the field of aviation is the effects of Cold Soaked Frost. It is hazardous problem for which various solutions are the responsibility of several aviation administrations. Owing to the lack of computational research on frost formation such as on a wing surface, an advanced model for predicting frost thickness under a various range of flow conditions was developed and validated in this study. In evaluating the growth rate of the solid layer, the relation between the partial vapor pressure and the saturation pressure was used to determine the supersaturation degree. Frost thickness was assumed on the basis that the mass transfer effects associated with the diffusivity of the vapor are related mainly to the growth rate of crystallization. We performed a favorable regression procedure to find constant values for the correlation of the growth rate. The proposed frost thickness model was validated through the comparison of the simulation results with various experimental data for the case of a flat plate. The results obtained using the proposed model agree satisfactorily with the experimental data.
