Abstract
The influence of measurement methods with some measuring conditions on
droplet coalescence and solution were experimentally investigated to measure
the droplet size more accurately by the immersion liquid method. In the case of
the sedimentation method, the experimental result shows that captured droplets
coalesce and dissolve even in the immersion liquid as well as on its surface. It
was also found that the solution of captured droplets into the immersion liquid
considerably decreases by interrupting its surface from the air. Moreover, the
influence of the immersion liquid viscosity on the droplet coalescence can be
neglected within the very short shutter opening period (TS ≤ 103ms) irrespective
of the sedimentation method or the hanging one. So, it is desirable to measure
the droplet size as soon as possible after the droplets were completely immersed
into the low viscosity immersion liquid, to prevent the effects of the droplet
coalescence and solution into the immersion liquid.
Keywords: immersion liquid method, sedimentation method, hanging method,
measurement technique, droplet coalescence, droplet solution, Sauter mean
diameter.
