Welcome! You are (+ 10629 )-th visitor of this site. (since 11 Jan. 2000 )

Speciality:

Computational fluid dynamics. My major interest is computational and mathematical analysis on fluid flow phenomena. Recently, I focus my attention to the investigation of Saffman equation of dusty gas: one typical model of multi-phase flow with two-fluids description. This model will be applied to simulate ice accretion on a body or blood flow phenomena.

At the same time, I am also interested in Object-oriented modeling and attempt to apply this approarch to computational fluid dynamics.

Lectures:

For graduate students

Special Lecture of Numerical Analysis II

For undergraduate students

Modeling for system
Fluid dynamics for Biomolecular functional engineering
Electromagnetism for Beginners

Education:

　 1985: Master Degree of the University of Tokyo.
