AI Technical Summary
Existing ejectors suffer from problems such as long mixing paths, weak radial mixing, and unadjustable unsteady swirling disturbance intensity, resulting in limited improvement in mixing efficiency and insufficient adaptability to operating conditions.
A rotating disturbance mechanism, including a rotating center body and adjustable blades, is set in the mixing channel to enhance the shearing effect and turbulent diffusion between airflows by forming unsteady swirling disturbances, and the intensity and frequency of the swirling flow are adjusted by the blade mounting angle adjustment mechanism.
It improves airflow mixing efficiency, enhances flow field uniformity and operational stability, adapts to different operating conditions, reduces flow loss and flow resistance, and broadens the efficient operating range of the device.
