Visualization and size-measurement of droplets generated by Flow Blurring® in a high-pressure environment
(Taylor & Francis, 2018)
Flow Blurring® (FB) atomization is a highly efficient method to produce aerosols. It originates from an unexpected turbulent back flow motion in the interior of the atomizer. The onset for the appearance of such pattern ...

Dynamics of formation of poly(vinyl alcohol) filaments with an energetically efficient micro-mixing mechanism
(American Institute of Physics Publishing (AIP), 2020-12)
We present a pneumatic approach for massive production of poly(vinyl alcohol) (PVA) filaments based on a mixing mechanism at the micrometer scale using so-called Flow Blurring (FB) atomizers. This micro-mixing is triggered ...
