State-of-the-art of frost deposition on flat surfaces - Communication au 24ème Congrès International du Froid (août 2015, Yokohama, Japon)

Résumé et principaux résultats

This paper presents a comparative study of predictive methods of frost growth on flat surfaces. The study focuses on the comparison between 4 different existing theoretical models or empirical correlations and a database gathering almost 556 test points available in the literature. Impacts of air velocity, relative humidity and wall temperature are studied. The latter is found to have a significant impact on frost development. Quantitative and qualitative analysis of the predictive methods are proposed. This study leads to the identification of the main issues in the field of modelling of frost deposition on flat plates.
