A one-dimensional model for frost formation on a cold flat surface

In the citing paper

“Fig. 6b suggests that the model describes the measured frost surface temperature reasonably well except for some overprediction in the case of φ = 50% (where the data exhibit somewhat irregular behavior for times below about 40 min).”

In the citing paper

“Generally reasonable agreement is achieved between the model and the measurements for the frost thickness at the three values of φ = 50, 70 and 80% (Fig. 6a), although it must be admitted that the model somewhat underpredicts the data.”

In the citing paper

“At φ = 80%, the measured frost surface temperature increases to about -4 ºC, which is relatively close to the melting temperature.”

In the citing paper

“In the case of φ =50%, the model satisfactorily predicts that data up to t = 90 min, beyond which the data show a small jump in frost thickness.”

In the citing paper

“The measurements suggest that as the air velocity increases the frost thickness increases, with the data for V = 0.5 m/s and V = 1m/s approach each other for times in excess of about 110 minutes.”

In the citing paper

“Existing frosting models have focused on predicting the characteristics of heat and mass transfer at the surfaces of basic geometries, such as a flat plate or cylindrical surface [1-12].”

In the citing paper

“According to their correlations [9,10,11] frost thermal conductivity varies with its density.”

In the citing paper

“Therefore, frost formation on flat plate and cylindrical surface is relatively well known and can be predicted reliably with existing models and correlations.”

In the citing paper

“relative to experiments, the average relative deviations are 17.01% for these representative literature models”

In the citing paper

“Lee et al. [11] presented a model that only considered the frost layer when calculating the frost formation on a cold flat surface.”

In the citing paper

“The model assumed that the humid air was saturated at the frost surface, while Webb and coworker [7,12] assumed that the humid air was supersaturated at the frost surface.”

In the citing paper

“In 1997, this method was used for the validation of the developed one-dimensional model for the frost formation on a cold flat surface by Lee et al. [44].”

In the citing paper

“the probe of the digital micrometer was made of acrylic resin to prevent frost from melting when it would come in contact with the frost surface.”

In the citing paper

“the frost thickness was decreased along the air flow direction, but they indicated the difference in frost thickness along air flow direction was negligible when the air velocity was higher than 2 m/s.”
