Simulation and Experiment on Droplet Volume for the Needle-Type Piezoelectric Jetting Dispenser
Micromachines, 2019 The needle-type piezoelectric jetting dispenser is widely applied in the microelectronics packaging field, and it is important to control the droplet size to ensure that the droplet jetting process is successful. In this study, we analyzed the influences

Droplet size distribution in homogeneous isotropic turbulence [PDF]
, 2011 We study the physics of droplet breakup in a statistically stationary homogeneous and isotropic turbulent flow by means of high resolution numerical investigations based on the multicomponent lattice Boltzmann method.

Effect of process parameters on emulsion stability and droplet size of pomegranate oil-in-water
Grasas y Aceites, 2021 The development of efficient emulsion is essential and requires a good understanding of the parameters that govern the formation and stability of the emulsion. The droplet size significantly affects the stability of the emulsion.

Colloids and InterfacesThe design of emulsions at the nanoscale is a significant application of nanotechnology. For spherical droplets and a given volume of dispersed phase, the nanometre size of droplets inversely increases the total area, A=3Vr, allowing greater contact with

Dynamics of Vesicle Formation from Lipid Droplet: Mechanism and Controllability
, 2009 A coarse-grained model developed by Marrink et al. [J. Phys. Chem. B 111, 7812 (2007)] is applied to investigate vesiculation of lipid [dipalmitoylphosphatidylcholine (DPPC)] droplets in water.

Lattice Boltzmann simulation of droplet behaviour in microfluidic devices [PDF]
, 2008 We developed a lattice Boltzmann model to investigate the droplet dynamics in microfluidic devices. In our model, a stress-free boundary condition was proposed to conserve the total mass of flow system and improve the numerical stability for flows with ...

Vibration of submillimeter-size supported droplets
Physical Review E, 2006 We study the fundamental vibration mode of supported submillimeter-size droplets. Using an analogy with a simple oscillator we derive a semianalytical expression for the eigenfrequency and the scaling law of the energy dissipation within the droplet. The experimental results obtained for mercury drops deposited on glass are compared with the model. The

Comparison of droplet distributions from fluidic and impact sprinklers [PDF]
Frontiers of Agricultural Science and Engineering, 2015 To adapt to the trend toward low-energy precision irrigation, the droplet distributions for two new prototype sprinklers, outside signal sprinkler (OS) and fluidic sprinkler (FS), were compared with impact sprinkler (IS).

Nuclear Engineering and Technology, 2019 Droplet size and distribution are important parameters determining venturi scrubber performance. In this paper, we proposed physical models for a maximum stable droplet size prediction and upper limit log-normal (ULLN) distribution parameters.

Convective Ripening and Initiation of Rainfall
, 2014 This paper discusses the evolution of the droplet size distribution for a liquid-in-gas aerosol contained in a Rayleigh-B\'enard cell. It introduces a non-collisional model for broadening the droplet size distribution, termed 'convective ripening'.
