Frost characteristics and heat transfer on a flat plate under freeze operating conditions. 2. Numerical modelling and comparison with data.

Author(s) : CHEN H., BESANT R. W., TAO Y. X.

Summary

An existing numerical model for frost growth as a porous media is modified to include boundary conditions for a relatively high-density frost layer adjacent to a cold plate and turbulent airflow over a rough frost-air interface. Low-density frost grows on top of this high-density surface layer. Simulation results compare well with the data for selected test conditions where experimental uncertainty is small. When the experimental uncertainty is small, a validated physical/numerical model may be the best means of interpreting the physical nature of frost growth and extrapolating a limited database for frost growth.
