Abstract
Ice melting front thickness has been estimated by studying the kinetics of thawed water accumulation during melting of ice balls with different sizes at room temperature (≈22°C) taking into account the temperature measured both on the surface and inside of the balls. The supplied heat flux is absorbed as the latent heat of fusion by an ice layer, which we define as the melting front. A model of this process has been formulated to describe the kinetics of ice ball melting. It has been assumed that the heat is supplied through the entire ice ball surface, the area of which decreases in the course of melting. The temperatures measured on the surface and inside of the balls have turned out to be ~0.4 and 0°С, respectively. Corrections associated with water evaporation have been taken into account. The fit of the experimental data according to the proposed model has made it possible to estimate the thickness of the ice melting front at room temperature. It has appeared to be approximately 3.2–3.6 mm.
期刊介绍：
Colloid Journal (Kolloidnyi Zhurnal) is the only journal in Russia that publishes the results of research in the area of chemical science dealing with the disperse state of matter and surface phenomena in disperse systems. The journal covers experimental and theoretical works on a great variety of colloid and surface phenomena: the structure and properties of interfaces; adsorption phenomena and structure of adsorption layers of surfactants; capillary phenomena; wetting films; wetting and spreading; and detergency. The formation of colloid systems, their molecular-kinetic and optical properties, surface forces, interaction of colloidal particles, stabilization, and criteria of stability loss of different disperse systems (lyosols and aerosols, suspensions, emulsions, foams, and micellar systems) are also topics of the journal. Colloid Journal also includes the phenomena of electro- and diffusiophoresis, electro- and thermoosmosis, and capillary and reverse osmosis, i.e., phenomena dealing with the existence of diffusion layers of molecules and ions in the vicinity of the interface.
