| Abstract: |
| The main research object is the hollow blade of a vertical horizontal wave turbine(WTHB).A combination of momentum theory,buckling failure theory and three-dimensional numerical simulation is adopted to investigate the radial compressive stress generated by WTHB during non-single wave processes.In addition,various factors affect the buckling failure of the hollow blade,such as unidirectional wave force,two-way wave force,hydrodynamic angle of attack,and double support point distribution of the wings.The results show that the stability of the hollow blades is obviously better than that of the traditional one-way wave;the angle of attack at 40° is optimal value of the obtained hydrodynamic angle of attack,but compared with angle of attack of 20°,there is larger radial bucking deformation value.The double-support point of the hollow blades has a greater influence on the overall ultimate buckling mode. |
