文摘
- •
A modified impulse turbine within rotor blade setting angle is proposed for asymmetrical air flow velocity amplitude conditions.
- •
Numerical model is set up based on Fluent and validated by corresponding experimental data.
- •
Flow field and pressure distribution around the rotor blade are illustrated.
- •
Mean efficiency in a wave cycle demonstrates that a 5° setting angle of rotor blade is optimum for the inhalation to exhalation velocity amplitude ratio 0.6.
