Analysis of the mechanism for the three-dimensional hydrofoil and propeller contacting the ice body
Abstract Polar propellers working in frozen waters would suffer the threaten of ice loads. However, the complex shape of the blade brings difficulties to the correlation analysis of the propeller-ice contacting phenomena and ice loads. This paper utilized a three-dimensional wing structure to simplify the propeller blade shape to a certain extent. The three-dimensional wing was constructed by selecting a foil profile at 0.75R of a certain PC3 level ice-class propeller (IACS, 2016) and extended the profile in the spanwise direction. Then a propeller-ice contacting model and a wing-ice contacting model were established based on the state-based peridynamics theory. The established models are verified by the model tests results. The hydrofoil shape-controlling parameters, including the attack angle, the thickness distribution, and the bow distribution of the hydrofoil were further studied in the research to investigate their effects on the propeller-ice contacting proceedings.
