摘要：

The effects of wind speed and inlet wind directions on marine gas turbine inlet icing are studied by numerical simulation. The flow field, water impact coefficient, and icing law in the inlet under different wind speeds and inlet wind directions are also analyzed. The results showed that the main icing positions include the arc area of the inlet shaft and the shrinking part of the connection between the inlet shaft and the pressure-stabilizing box. The droplet collection efficiency and average icing coefficient under low wind speed conditions are higher than those under high wind speed conditions so that droplets easily freeze in the air inlet. When the wind direction is 135°, the mass of the ice deposition is the largest in the air inlet. © 2023 Editorial Board of Journal of Harbin Engineering. All rights reserved.
