Abstract. The paper presents the modeling of heat transfer and ice<br />

formation around the pipes of a skating rink by the finite element method. In<br />

case of skating rinks equipped with pipe registers, the temperature field during<br />

the ice formation process can be modeled by analytical methods. Thus the paper<br />

advances a method for calculating the temperature and distribution of heat<br />

around the track pipes The heat transfer in the skating rink track is<br />

nonstationary and phase changing.<br />

Key words: solidification, ice, skating rink, heat transfer, phase changing.<br />

1. Introduction<br />

The problem of melting and solidification of substances, regarded in<br />

terms of determining the temperature field in solid and liquid phases and solid<br />

– liquid interface propagation , has aroused considerable (theoretical and<br />

practical) interest , because the conductive transfer processes accompanied by<br />

the phenomenon of phase transition are present in many applications, such as<br />

solidification of ingots, controlled solidification of alloys to obtain certain<br />

metallographic structures, food refrugeration , soil freezing and defreezing, the<br />

ablation phenomenon under aerodynamic heating, thermal storage with phase<br />

change, etc. Mathematical modeling of this phenomenon and especially<br />
