Numerical prediction of ventilation patterns and thermal processes in ice rinks

A numerical simulation of the heat and mass transfer phenomena in a ventilated ice rink has been carried out using the standard κ-ɛ turbulence model. The complexity of the geometry has been taken into account by considering elements such as the plastic protection panels which have a significant effect on the flow field. The results calculated for four different configurations show the flow pattern, the isotherms and the lines of constant absolute and relative humidity. Values of the effective draft temperature are presented for several positions in the zone occupied by the spectators. The heat losses through the walls and ceiling as well as the latent, convective and radiative heat flux into the ice are presented and analyzed.
