Smoothed Particle Hydrodynamics (SPH) was applied to simulate the three-phase phenomenon of ice formation on a solid surface exposed to air flow in three dimensions. The air flow carried sub-cooled water droplets. The method was verified by comparing its prediction of the rate of ice formed with the literature data. The effect of air flow velocity on the amount and rate of ice formation was investigated. It was seen that with increasing the air flow velocity the amount of formed ice was also increased. Moreover, two defrosting schedules of constant heat flux on the surface were examined. According to the results, the reduction percent of ice formation was increased by increasing the heat flux and the reductions were more significant at lower air velocities.
