Research in this chair is focused
on the analysis of phenomena in particle handling processes and on the
development of the methods for the rational handling of them. Particles are widely used in various
fields and the particle behavior varies complicatedly depending on the conditions;
thus, a full understanding is needed from the viewpoint of the effective
application of fine particles and for environmental protection. In particular, for
dry powder systems, i) analysis of dynamic behavior
of particles, ii) control of particle adhesion, and iii) evaluation of the
total property including the effect of static electricity should be
Electrification of particles
of particles is a fundamental phenomenon occurring in powder handling
processes, and the electrostatic force acting on particles significantly
affects the particle behavior.
Therefore, the control of the charging is important for powder handling. In addition, applications using charged
particles have been widely developed, e.g. electro-photography, dry powder
coating, and electrostatic separation.
Since dispersion, agglomeration, and transport of charged particles can
be remotely controlled using electrostatic force, the development of new
applications is expected. To
realize it, a correct understanding of the particle charging, charge
distribution control, particle movement control, and relevant online
measurement techniques are required.
(1) Clarification of the mechanism of
particle charging in a steady electric field.
(2) Control of the movement of charged particles under an
unsteady electric field with spatial and temporal variation.
Analysis of the simultaneous transfer of mass and charge in a powder bed.
Development of a high-accuracy measurement system for charge distribution of
Evaluation of Adhesion and flowability of
and particle-wall interaction forces are important factors directly affecting
powder handling, and it is required to develop appropriate methods for
measuring adhesive property between primary particles and between aggregate
particles, and for evaluating the flowability.
(1) Analysis of adhesive strength
distributions in various complex fields.
(2) Analysis of flowability profiles.
Mechanical handling of nano and submicron particles
highly functional products, the demand for using nano
and submicron particles is increasing every year. Particle adhesiveness increases with
decreasing particle diameter and powder handling becomes more difficult. In particular, for
small particles less than 1 m in diameter, the
problems are serious, and it is urgent to develop new techniques, as well as to
analyze of the particle behavior.
(1) Development of micro-feeder for
nanoparticles using a shear vibration.
(2) Development of a system for particle dispersion
using an ultrasonic vibration and airflow.
Development of a pneumatic transport system for nanoparticles.
