Temperature field of metal structures of transport facilities with a thin protective coating

Abstract

A study of the temperature field in metal structures of transport facilities with corrosion-resistant coating under the conditions of changes in ambient temperature has been conducted. The results of experimentally determined temperature distribution in the surface vicinity of a galvanized metal sheet are presented. The data were obtained over the day at positive and negative surface temperatures. Given a generalized boundary condition for the heat conduction problem, with a solid heated by a localized heat flow through a thin coating, there has been obtained and analyzed a temperature field. The temperature distribution across the surface outside the heating region during heat propagation along the coating was analyzed. Experimental data and model calculations, as well as temperature calculations allowing for the coating and not, have been compared. It has been established that the effect of coating on the temperature distribution in the metal structure, when the solid is heated by a localized heat flow through a thin coating, is insignificant.

Numerical modeling of heat and mass transfer processes in a capillary-porous body during contact drying

“…A kinetic approach based on a modified chain of BBGKI equations for nonequilibrium particle distribution functions is used in [2] to describe the ion transfer processes in the ionic solution-porous medium system. The issue of accounting for the temperature inhomogeneity in the model of heat transfer for the structure being attributed to the heating-cooling cycles, or nonuniform heating, is considered in [3]. Stefan's linear problem for drying capillary-porous material is solved under quasi-averaged formulation in [4].…”
