Abstract：According to the principle of hydrodynamic instabilities, a new rotary atomizer was designed and its strength was checked by the finite element software of ANSYS workbench. Besides, the atomization experiments were conducted on the device based on the technology of high-speed shadowgraph imaging and image processing with MATLAB. The results show that the maximum deformation is located at the disc and the stress is mainly concentrated at the support of the experimental device. The maximum stress of the device is 13.6 MPa, which is much less than the yield strength of the applied material. At the pump flow of 640 L/h and the disc speed of 200-800 r/min, the effect of ligaments and the thickness of liquid films are reduced significantly with the increase of the disc speed, and the average diameter of the droplets is reduced from 1 240 μm to 688 μm, which meant that the atomization effect of the device has been increased a lot with the increase of RPM. This work can provide a reference for further optimization of the device.
