Numerical Simulation on Vortex Shedding of Propeller

  • Based on Arbitrary LagrangeEuler(ALE) method,the Finite Element model of the fluidpropeller interaction was built using LSDYNA software.The hydrodynamic characters and mechanical performance of structure(fluid resultant velocity and structure internal stress of blade) were studied under the incoming flow of fixed blade of propeller,analyzing the internal varying stress of blade and vortex motion behind the propeller.The ressults show that irregular surface of blade result in vortex shedding phenomenon behind the propeller.And the element stress of blade was determined by its′ thickness and the distance to the constraint location.
