Modeling of thermal processes in anti-icing gratings for arctic purposes

Abstract

The problem of modeling thermal processes in anti-icing gratings, which are used in arctic conditions, is considered. The task is of practical importance, including for the design of air intake grilles for ship systems operating in arctic conditions. A mathematical model of thermal processes is presented, which takes into account the processes of heat transfer in the lattice due to the thermal conductivity of its internal elements, due to convective heat exchange with the external air, due to heat release during electric heating, and also due to phase transformations during icing and melting of ice. The problem is solved in a three-dimensional formulation, using a software package developed at Bauman Moscow State Technical University. Some results of numerical simulation are presented.
