MS7-03 - Particle-laden flows
Particle-laden flows refer to a kind of two-phase fluid flow in which one of the phases is
continuously connected and the other phase is made up of small immiscible particles.
Particle-laden flows modeling has a wide variety of scientific and engineering applications:
dispersion of contamination in the atmosphere, fluidization in combustion processes,
deposition of aerosols in aerosol drugs, spread of virus in the air, rain formation in clouds,
sand and dust storms, protoplanetary disks, volcanic eruptions, geological sedimentation
processes, pharmaceutical sprays, liquid-fueled combustion, solid rocket motors, coal
furnaces, and particle-based solar receivers are examples of engineering processes that involve
particle-laden flows among many others. In addition, the study of particle-laden flows is also
the basis for the simulation of active fluids, in which the particles themselves move with their
own energy.
The multi-scale and nonlinear interactions between the carrier and the dispersed phases lead
to complex flow physics and pose unique modeling challenges. Also, many of these flows
involve turbulence. The simultaneous presence of two of the most challenging topics in fluid
mechanics, namely multiphase flows and turbulence, is still an unsolved problem.
This Mini-symposia hopes to bring together different researchers in the modeling of fluids
with particles, from the simplest cases where the particles simply move with the fluid, to the
most complicated cases where the particles do not follow the fluid velocity. Contributions to
the theoretical development of the Eulerian-Eulerian and Lagrangian-Eulerian approaches but
also their recent applications to challenging industrial and engineering case studies are
welcome.
