Effect of the Installation Angle of Nozzle on the Atomizing Performance of Air-Assisted Spraying Dust Suppression Device

Investigation of the JJPW-G100 air-assisted spraying dust suppression device was performed to obtain reasonable installation angle nozzle in device. First, an equal-scale physical model established, and then effect on atomizing performance investigated in-depth via numerical simulation. Results showed that imposed no significant range device, while initial falling spray field increased with increasing angle. At over 45°, loss droplets at outlet air cylinder disappeared. Mean droplet size angle, which first dropped range. The optimal determined as under can be effectively prevented, maintain a small large
