INDEX
Our
research is focused on analyzing the phenomena that occur during powder
processes and on developing new handling methods for powders. Although fine
particles are widely used in industry, their behavior is complicated and varies
according to the conditions used; thus, a full understanding is needed from the
viewpoints of the advanced applications of fine particles as well as
environmental protection. In particular, the analysis of the dynamic behavior
of particles and the evaluation of powder properties such as particle adhesion
and electrification are important for fine-particle handling in gases.
Fundamentals and applications of particle
electrification
The contact electrification of particles is a fundamental phenomenon that
occurs during powder handling processes, and the electrostatic forces acting on
particles significantly affect particle behavior; thus, the control of particle
charging is important for powder handling operations. In fact, applications for
charged particles have been widely developed, e.g., electro-photography, dry
powder coating, and electrostatic separation. As operations such as dispersion,
agglomeration, and particle transport can be remotely controlled by
electro-static forces, further technological innovations are expected in this
direction. To realize the full potential of the existing technology, an
in-depth under-standing of particle charging, charge distribution control, particle
movement control, and relevant online measurement techniques is needed.
1. Particle charging and
levitation with UV irradiation and electrostatic field.
2. Particle electrostatic charging by atmospheric pressure
low-temperature plasma.
3. Analysis of
triboelectric charging of fine particles.
4. Development
of a particle charge controller using centrifugal force and its application.
5. Characterization
of fine particles triboelectrically charged in gas–solid pipe flow.
6. Characterization
of particles triboelectrically charged by a two-stage system with vibrations
and external electric fields.
Evaluation of Adhesion
and flowability of particles
Particle–particle and particle–wall interaction forces are important
factors that directly affect powder handling, and appropriate methods need to
be developed for measuring the adhesive property between primary particles or
agglomerated particles and for evaluating the flowability of particles.
1DAnalysis of adhesive strength distributions
of particles subjected to various external forces.
2DAnalysis of flowability profiles.
Mechanical handling of nano and submicron
particles
The demand for submicron- and nanoparticles is growing on account of the
need to produce highly functional products. However, their adhesiveness
increases with decreasing particle diameter, and as a result, powder handling
becomes more complex for small particle diameters. In
particular, for particles having a diameter of less than 1 ƒÊm, the complications due to adhesiveness are pronounced
and it is therefore imperative to develop new techniques as well as analyze
particle behavior for overcoming these issues.
1. Control of the movement of
fine particles using multiple vibration modes.
2. Development of a novel fluidized bed system using vibration
convection mechanism.
3. Development of micro-feeding of nanoparticles based on
vibration shear flow.
4. Development of a pneumatic transport system for nanoparticles.
