Summary

A numerical model was developed to approximate the rate of ice-crystal growth in a falling film flowing down a cooled vertical plate for assumed laminar flow. Nusselt numbers and overall heat-transfer coefficients between the film and cooled plate and ice-crystal growth rates were calculated for different film thicknesses, initial ice-crystal diameters, and Stefan numbers. Nusselt number and ice-crystal growth rate were found to be dependent upon film thickness (flow rate), initial ice number concentration, and Stefan number. Quantitative comparisons of calculated heat-transfer coefficients to some previous experimental data show reasonable agreement.
