Thermodynamic model of ice collar for hydrotechnical construction

Arctic development is one of the priorities for the country. For this, it is necessary both to develop new normative documentation on standardization and to improve existing norms and standards. The Arctic region is complex in terms of weather and environmental conditions. Environmental loads and actions on hydraulic structures are most important and primarily include impacts from ice. Ice impacts can be of a very different nature and therefore are not fully reflected in the normative documents. The formation of an ice collar is one of the types of freezing on the submerged hydraulic structures. Ice collar is a thicker ice around structure due to the high thermal conduction through the structure. This ice is formed due to the heat flow through the body of the structure and can be calculated. Analytical calculation of the ice collar is difficult to perform, so it is proposed to use a thermodynamic model for numerical simulation.
