Abstract

The present work is an experimental investigation of heat and mass transfer with frost growth over flat plate surface. This study focuses on the most important factors affecting the frost formation process, i.e. the surrounding air temperature, air humidity and air velocity, and the plate surface temperature. Experiments were carried out using a purpose-built apparatus to acquire data to measure the thickness of frost layer, and surface temperature of frost layer. Results showed that the plate surface temperature and air velocity have the greatest effect on frost layer thickness and heat and mass transfer coefficients, relative to the air humidity and air temperature. Comparisons between present exponential results and previous work relevant to this study show a fairly good agreement.
