Medical air-compression nebulizers deliver atomized medication to the lungs, providing rapid and painless treatment for respiratory diseases. However, size of most droplets is around 10 μm, limiting drug deposition in lower airways alveoli, with increasing proportion sub-5 μm remaining challenging. In this work, finite element analysis was employed model effects gas flow rate, liquid channel width, broken baffle structure on droplet distribution, aiming optimize symmetrical parameters operating conditions. A novel compression atomizer developed experimentally evaluated, incorporating an improved crushing baffle. Following modification, increased from 54.6% 59.25%, representing a 4.65% enhancement generation droplets. The rate concentration distribution were systematically investigated further atomization performance. results demonstrated significant increase droplets, thereby enhancing delivery efficiency tract improving efficacy
