Abstract:

This report, prepared by members of the Working Group on Thermal Regimes of the Section on Ice Research and Engineering of the International Association for Hydraulic Research, is a comprehensive overview of frazil ice. Starting from the initial nucleation of single frazil ice crystals to the formation of ice covers that may be many kilometers long, the physics and evolution of frazil ice in natural water bodies are described. Laboratory experiments conducted over the last 30 years on frazil ice dynamics and other aspects of frazil are described and classified. A physically based, quantitative model that describes the dynamic evolution of the crystal size distribution function is presented. In addition, the development of numerical models of frazil ice in oceans and rivers is discussed and their results described. This report serves as a review of the state of the art of the present understanding of frazil, and the extensive references are a comprehensive resource.
