TLDR

An experimental study was carried out on heat and mass transfer rates, growth rates and the density of frost layers on a flat plate in forced convection conditions. The density and thickness of the frost layers were correlated by the dimensionless parameters introduced in the authors' previous paper [6]. Measured density and thickness of the frost layers are compared with those in natural convection conditions and with those measured by other investigators. It is shown that these parameters can also be used to generalize the density and growth rates of frost layers developed under forced convection conditions.read more

Review of restraint frost method on cold surface
TL;DR: In this paper, the authors divided the factors on frosting into three categories: the characteristics of the moist air, the features of the cold surfaces, and the interaction between the formed frost and the cold surface (electric field, ultrasonic wave, magnetic field, oscillation effects).

Equation of the growth rate of frost forming on cooled surfaces
TL;DR: Based on accurate measurements of a cooled tube, the frost thickness turns out to be independent of the variables commonly significant on mass transfer, such as Reynolds number and vapor pressure difference as discussed by the authors, which is in good agreement with experimental results of previous investigators.

A Study of Extended Surface Heat Exchange with Frosting : 1st Report, Overall Heat Transfer Characteristics
TL;DR: In this paper, the effect of deposition on heat and mass transfer was investigated both theoretically and experimentally in a finned tube type heat exchanger under frosting conditions, and the predicted results were in good agreement with the experimental data obtained under the two typical operating conditions, i.e., the constant air flow rate and the constant revolution number of blower.
