The formation of drops of particulate suspensions composed of spherical, neutrally buoyant, noncolloidal particles in a viscous liquid is examined experimentally. The suspensions are investigated over a range of particle volume fractions, φ=nπdp3/6 where n is the particle number density and dp is the particle diameter (dp=212–250 μm in most of the experiments), and for flow through three tubes of outer diameters d=0.16, 0.32 and 0.64 cm; the corresponding inner diameters are 0.10, 0.22, and 0… 
Modelling capillary break-up of particulate suspensions
We have constructed a simple one-dimensional model of capillary break-up to demonstrate the thinning behaviour of particulate suspensions previously observed in experiments. The presence of particles
Accelerated drop detachment in granular suspensions
We experimentally study the detachment of drops of granular suspensions using a density matched model suspension with varying grain volume fraction (ϕ = 15% to 55%) and grain diameter (d = 20 μm to
Capillary breakup of suspensions near pinch-off
We present new findings on how the presence of particles alters the pinch-off dynamics of a liquid bridge. For moderate concentrations, suspensions initially behave as a viscous liquid with dynamics
Particles accelerate the detachment of viscous liquids
During detachment of a viscous fluid extruded from a nozzle, a filament linking the droplet to the latter is formed. Under the effect of surface tension, the filament thins until pinch-off and final

Dynamics of sheared droplets filled with non-Brownian particles
The dynamics of single droplets containing non-Brownian particles are studied. The particle over droplet size ratio (r/R) is changed by using different particle sizes (r/R = 0.02–0.4). Additionally,
Dip-coating of suspensions.
TLDR
This article studies the Landau-Levich problem in the case of a suspension of non-Brownian particles at moderate volume fraction 10% < φ < 41%.
Droplet detachment and pinch-off of bidisperse particulate suspensions.
TLDR
This paper experimentally investigates the thinning and pinch-off of drops of suspensions with two different sizes of particles, and explains how the bidisperse particle size distribution lowers the viscosity by making the packing more efficient, which speeds up thethinning.
Generation of inkjet droplet of suspension in polymer solution
In the present study the generation of inkjet drops of suspensions of spherical particles in polyvinylpyrrolidone (PVP) solution in 1-heptanol is investigated experimentally. The particle size was 2
