Numerical analysis results show that the designed blade structure was safe, and the value of stress and strain was low.
In this study, the proposed blade structure was confirmed to be safe and stable under various load conditions, including the extreme load conditions.
Although the 3-blade structure is clearly visible at locations away from the focal point, it loses its fine feature in its intensity pattern at the focal point, where the intensity gradient is needed for forming the trap.
Performance indices of different fan blade structures were compared.
In this paper the failure behaviour of composite materials in the skin-stiffener of wind turbine blade structures are investigated.
A Kenics® KMX static mixer that has curved-open blade internal structure was investigated to study its hydrodynamic performance related to residence time distribution and liquid holdup in a gas/liquid system.
The quasi-static and fatigue simulation results demonstrate the ability of the model to predict the evolution of damage in the critical regions of the blade structure, which is an important contribution and essential for increasing the accuracy of damage tolerance analyses and for certification of composite structures.
If bird collisions with wind turbine blades can be monitored, birds could quickly be rescued, and the blade structure could be examined to assess whether it has significant damage.
The results show that there is an obvious restriction relation between the pressure and tangential velocity distribution caused by the swirl blade, a balanced point (optimized structure) is necessary to achieve the purpose of condensation and separation of CO2 droplets.
Structure is important for small blades in another way: starting depends on the aerodynamic torque generated by the blade shape and is improved by a low blade inertia, J B, which depends on shape, material, and manufacturing technique.
Even though the blade surface shape is determined largely by aerodynamic requirements, the structure is very important.
