Spray drying and electrospraying are well-established drying processes that already have
proven their value in the pharmaceutical field. However, there is currently still a lack of …

In order to understand the droplet micro-explosions occurring during single droplet
combustion of the flame spray pyrolysis (FSP) precursor/solvent solutions, the optical …

The transient evaporation characteristics of free-falling ethanol droplets under ambient
temperatures of 373–473 K are investigated with the rainbow technique. The size and …

Phase change in multiphase flows occurs in many natural and industrial applications, eg,
rain formation, internal combustion engines, heat exchangers, multiphase reactors, etc. In …

Size measurement of micron-sized metal droplet is of great demand in industrial
applications, eg, 3D printing and metal propellant. A dual-beam interferometric particle …

Quantifying the evaporation rate of droplets is of great importance in many applications and
this is especially true if the evaporation occurs in a rapidly changing environment, such that …

Evaporation characteristics of interacting fuel droplets under the joint effect of ambient
pressure, temperature and droplet size and spacing are critical to combustor design and …

The accurate measurements of droplet temperature, size and evaporation rate are of great
importance to characterize the heat and mass transfer during evaporation/condensation …

We have developed phase interferometric particle imaging (PHIPI) of Mie scattering to
simultaneously measure the spherical and transparent droplet size at the micron scale and …

A vector ray-tracing model (VRT) has been developed to compute the optical caustics
associated with the primary rainbow for an oblate spheroidal water drop illuminated by a …
