| Abstract: | To study the atomization characteristics of fan spray nozzle,five fan spray nozzles with different spraying angle,different outlet form and different size were designed.An experimental bed system was built.The spraying experiment for the nozzles was performed under the design conditions.In the aspects of mass flow and atomization characteristics,the influence of gas-liquid ratio and nozzle structure on flow coefficient of nozzle and distribution of atomization particles was analyzed.The qualitative influence trend of nozzle structure on atomization characteristics is given. |
