Influence of Spinner Shape on Droplet Impact over Rotating Spinners

Droplet impact affects water collection, which is the key to investigating icing process on an aero-engine spinner. Different from a stationary spinner, droplet affected by Coriolis acceleration and centrifugal rotating spinners, showing different dynamics. Based Eulerian method, using coordinate system we numerically investigated characteristics three shapes of spinners ANSYS Fluent. The results indicate that area covered all windward surface conical only prior impingement limit elliptical spinner coniptical sensitivity collection inflow velocity declined in order In addition, region could effectively improve aerodynamic performance, as shown lower total pressure loss through This work relevant anti-icing
