A Mathematical Model for Predicting the Droplet Size of Micro-Fog Nozzle with Circular-Hole Rotating Core Based on Orthogonal Design

The circular-hole rotating core fog nozzle has excellent atomization performance and been widely used in the realm of spray dust. As part this study, a mathematical model was developed for predicting Sauter mean diameter (SMD) nozzles type. coaction between SMD three influencing factors axial distance, water supply pressure, outlet investigated based on customized spray’s experimental platform orthogonal design method. According to comparative analysis size range, pressure are parameters that affect nozzle, degree influence is distance > pressure. On basis, using multiple regression method predict nozzle. We analyzed results compared them value predicted by experiment results. change trend same, values were essentially average relative error just 16.11%. Accordingly, presented paper may be prediction calculation droplet micro-fog nozzles.
