Descrição: In order to realize the refined visualization of liquid sheet spray process and the accurate numerical calculation of spray characteristics,the numerical method based on adaptive mesh refinement technique and VOF method was established for pressure swirl injector. The method was able to capture the structure characteristics of the spray field,including the first spray and the second spray. And the spatial distribution and diameter distribution of droplets in the field could be obtained. The visual effect of droplets captured was almost lifelike.For the open-end swirl injector of given structure size,the spray characteristics,such as cone angle of liquid film and droplets average diameter SMD,have been calculated under the different flows and the different diameters of tangential orifices,and were compared with the breakup process images of conical liquid sheet photographed with high-speed photography and the droplets SMD measured by PDPA(phase doppler particle analyzer)system. The results are in good agreemen
