Computational Simulation of Transport Phenomena in Self-Heating Aluminosilicate Composites

Original language description

Self-heating ability of aluminosilicates influenced by an external electric source is in general negligible. It is due to the electrically non-conductive nature of such heterogeneous materials. However, the effective electrical conductivity of aluminosilicates can be significantly increased by addition of metal-based or carbon-based admixtures. Such enhancement can be subsequently utilized in self-heating applications, such as for preparation of pavements or parts of roads which are exposed to adverse weather conditions in winter seasons. In addition to necessary experimental measurements, it is important to determine self-heating ability of materials by means of theoretical modeling. In this paper, two-layer system of materials consisting of electrically conductive aluminosilicate (ECA) with embedded electrodes and protective layer made of concrete (C) was considered. Three FEM calculations were performed and results were mutually compared. In the first case, electrical conductivity was identical in all mesh points, whereas in the second and the third case different electrical conductivities according to the distribution of electrically conductive admixture in mesh points were used as input variables. It was observed that minimal and maximal temperature on ECA and C surface after 120 minutes of heating by 200 V power source is similar for all modeled cases.
