| Abstract: | Flexible blade can change its shape to fit different streams.Multi-node model dynamic equation was set up to its structural and characteristic.Combined with experiments,three models were set up for different positions.Based on UDF(User-Defined Function) to control dynamic mesh,several different running speeds of turbine were simulated in 3D.With three different models the hydrodynamic performance of flexible blade turbine was obtained,and the effects of velocity-ratio and chord-arc-ratio were also analyzed.... |
