- W2378206403 abstract "Based on Arbitrary Lagrangian-Eulerian method(ALE),according to the actual data of certain sound problems of screw propellers,a three-dimensional single gridding finite element model is established by taking the screw propeller blade section at 0.7R and the vortex happening at the blade section is studied.The numerical calculation results,experience formula results and actual measurement of vortex shedding frequency are compared with an emphasis on blade section structure response.The numerical calculation results show that vortex dropping happens on both the back of the blade section and blade surface;vortex shedding frequency and actual measure are close by the numerical calculation;there exists stress concentrating area in blade structure;the stress concentrating locations and peak value change regulations are related with vortex shedding." @default.
