@@The mathematical modeling and computation on physics and matters not only for natural sciences but also for social sciences are the main issue researched in our laboratory. Our labo. belongs to the division of the Applied Mathematical Science in Department of Computer and Mathematical Sciences.

@@Especially, multi-physics including not only fluids but also other physics such as chemical reactions, phase transitions, and so on are mathematically modeled. The numerical schemes optimized to the architectures of supercomputers and PC clusters are developed for solving the mathematical models. These models are formulated by a system of nonlinear partial differential equations. Advanced computer and software sciences are also employed to assist the research works.

@@As current studies in our labo., we are developing mainly two multiphysics computational fluid dynamics(CFD) codes, hNumerical Turbineh; a computational code for simulating whole flow fields in gas-turbines and steam-turbines with condensate phenomena, and gSupercritical-fluids Simulator (SFS)h; a flow simulator which can solve flows of arbitrary substance in gas, liquid and supercritical conditions with phase transitions. These CFD codes are being applied to energy and environmental studies. Several collaborative researches with industries and academies are now conducted using these codes.
