摘　　要：Ice formation in the harbours in arctic region such as in Finland is a problem in winter times. The air bubblers are often used for controlling the growth of ice near the harbour pier walls. This paper gives an in-depth description of the harbour ice problem and the applicability of the bubblers. A numerical method of flow and heat-transfer is used to predict the effectiveness of the air bubblers in controlling the ice accumulation in the harbours. Empirical models of formatting and melting the ice are presented and used in the numerical solutions. It shows that the numerical method can realistically predict the ice-melting effect of the air bubblers.Ice formation in the harbours in arctic region such as in Finland is a problem in winter times.
