چکیده
We present a novel device for generating suspension droplets and studying droplet impact against solid substrates. The proposed generator extends beyond previous designs by introducing hydraulic machinery that includes separate test containers. This eliminates mixing between the liquid above latch connects two containers, thus ensuring reliable clogless operation. can produce of controllable sizes 0.75 4.4 mm, contain particles 45 μm to 300 size. Repeatability tests show that, at constant control parameters, median relative size deviation from target value is ±0.9% maximum ±9.1%. also explore different collision scenarios, which we change spreading bouncing varying substrate wettability. In addition, shape stain resulting spatial distribution are found be sensitive particle

Observations of droplet impingement on a ceramic porous surface
The dynamic aspects of droplet impingement on a porous ceramic surface were studied experimentally. Single-shot flash photography was used to photographically record the deformation and spreading on the surface. The observations were made with ambient pressure (0.10 MPa), ambient temperature (cu. 22”C), initial droplet diameter (1.5 mm), and the impact Weber number (43) fixed. The primary param...
متن کاملWhen does a suspension droplet splash?
We investigate the impact of droplets of dense suspensions onto a solid substrate. We show that a global hydrodynamic balance is unable to predict the splash onset and propose to replace it by an energy balance at the level of the particles in the suspension. We experimentally verify that the resulting, particle-based Weber number gives a reliable, particle size and density dependent splash ons...

Analysis and modeling of droplet-droplet interaction and particle-droplet interaction in dispersions
Droplet (fluid) -droplet (fluid) interaction: A numerical investigation of binary droplet collisions in a gaseous phase has been conducted as part of the coalescence modeling project. A volume of fluid (VOF) based interface capturing method, which is characterized by introducing an extra artificial compression term into the volume-fraction transport equation, is employed to capture the liquid-g...
متن کاملEnabling Droplet Functionality on Anisotropic Ratchet Conveyors
Anisotropic ratchet conveyors (ARCs) are a recently developed microfluidic platform that transports liquid droplets through a passive, microfabricated surface pattern and applied orthogonal vibrations. In this work, three new functionalities are presented for controlling droplet transport on the ARC system. These devices can pause droplet transport (ARC gate), decide between two pathways of dro...
