  • Internal flow characteristics in Spill-return pressure-swirl atomizers 

    Malý, Milan; Sapík, Marcel; Cejpek, Ondřej; Lízal, František; Ondráček, Vladimír; Jícha, Miroslav; Jedelský, Jan (ILASS, 2019-09-04)
    The spray produced by pressure-swirl atomizers strongly depends on the character of their internal flow. Flow field inside a swirl chamber of small pressure-swirl spill-return atomizers was examined using high-speed imaging ...

  • Investigation of pressure swirl sprays using Volumetric PIV 

    Cejpek, Ondřej; Jedelský, Jan; Malý, Milan; Sapík, Marcel; Lízal, František; Koched, Amine (ILASS, 2019-09-04)
    The volumetric measurement technique (V3V-Flex©) was used to investigate the spray generated by two pressure swirl atomizers (PSAs). Both a simplex pressure swirl atomizer and a spill-return pressure swirl atomizer were ...

  • Selection of model liquid with refractive index matching for visualization of internal flow in a scaled atomizer model 

    Sapík, Marcel; Malý, Milan; Jedelský, Jan; Wigley, Graham; Cejpek, Ondřej (EDP Sciences, 2019-06-28)
    A scaled transparent modular model of pressure-swirl (PS) atomizer was prepared from cast PMMA (Poly(methyl methacrylate), Perspex™, Plexiglas™) with the aim to achieve a better understanding of internal flow and subsequent ...
