In this work. the possibility of using planar droplet sizing (PDS) based on laser-induced fluorescence (LIF) and Mie scattering was investigated within the framework of measuring the droplet Sauter mean diameter (SMD) of direct-injection spark-ignition (DISI) spray systems. For this purpose. LIF and Mie signals of monodisperse fuel droplets produced by a droplet generator were studied... https://pipingrockers.shop/product-category/amla-fruit/
