Liquid Transport Rates during Binary Collisions of Unequally-sized Particles

Publikation: Beitrag in einer FachzeitschriftArtikelForschungBegutachtung

Abstract

In this paper, we study the liquid transport between particles
of different sizes, as well as build a dynamic liquid bridge model to
predict liquid transport between these two particles. Specifically, the
drainage process of liquid adhering to two unequally-sized, non-porous
wet particles with difference initial film heights is simulated using
Direct Numerical Simulations (DNS). Same as in our previous work (Wu et
al., AIChE Journal, 2016, 62:1877-1897), we first provide an analytical
solution of a proposed dynamic liquid bridge model. We find that such an
analytical solution also describes liquid transport during collisions of
unequally-sized particles very well. Finally, we show that our proposed
model structure is sufficient to collapse all our direct numerical
simulation data, and hence is able to predict liquid transport rates in
these systems for a wide range of parameters.
