Welcome to Tsuji Laboratory
※Prof.Tsuji retired in March, 2007
Research in Tsuji lab. is performed in Tanaka lab. now.
So this homepage is not upgraded now...
Complex Particulate Systems, Department of Mechanophysics Engineering
- Complex systems with many particles moving, colliding and contacting each
other attract attention as a new research area. Examples of these complex
systems are from natural phenomena such as asteroids, avalanches, and sand
motion in deserts to particulate flows in various kinds of industrial
facilities. Conventional analyses dealing with these particulate flows regard an assemblage of particles as a fluid. Unfortunately several assumptions are
needed to solve equations in such approaches. As a result, research of each
particulate flow has developed using methodology special to the flow. Due to
remarkable computer power in recent years, it has become possible to calculate
motion of individual particles based on rigorous and simple equations and to
obtain entire motion as statistical properties of results of individual
particles. This approach is called "discrete particle method" which is easy to
understand because it uses mathematical models expressing actual phenomena as
we see. Currently Tsuji Laboratory deals with particulate flows in fluidized
beds but it is interested in any kinds of complex particulate flows.
