Detailed spray characteristics were obtained for a dual orifice atomizer using a phase Doppler particle analyzer(PDPA)in this study.The PDPA measured point data were integrated into the line averaged drop sizes over radial traverses and the cross section averaged sizes over the whole measured sections.The integrated PDPA data are greater as compared with the line of sight measurements given by a Malvern instrument,but reasonably consistent with the predictions based on the wave instability...

Detailed spray characteristics were obtained for a dual orifice atomizer using a phase Doppler particle analyzer(PDPA)in this study.The PDPA measured point data were integrated into the line averaged drop sizes over radial traverses and the cross section averaged sizes over the whole measured sections.The integrated PDPA data are greater as compared with the line of sight measurements given by a Malvern instrument,but reasonably consistent with the predictions based on the wave instability concept.The results from the investigation show that the PDPA is an effective instrument for providing a reliable approach of describing spray characteristics and determining the spraying quality.
