Field of Specialization
Combustion, Reactive Gas Dynamics, Internal Combustion Engines, Thermodynamics
Outline Activities
Main activities of research and education is on reactive gas dynamics. Studies on premixed laminar and turbulent combustion, stratified charge combustion have been done.
Premixed laminar flames at elevated pressures have been investigated using combustion vessel unique in Japan. The effects of pressure on flame instability, burning velocity and Markstein Number have been studied. Turbulent flames have also been investigated. Turbulent burning velocity have been modeled with turbulence Karlovitz number and Markstein number, or Lewis number. These studies have shown that the premixed flames under flame stretch are affected by thermo-diffusive effects.
Those combustion of coal gasification gas, bio-gas and alcohol derived from biomass are also examined in addition to hydrogen, methane, propane, iso-octane.
Numerical simulations with detailed chemical reaction mechanism or turbulent combustion model are carried out vigorously.
Nock phenomena in engine is also investigated to clarify its mechanism.
Some charecteristic phenomena of secondary flame, flame inertia, back-supported flame have been found by the investigation of stratified charge combustion.
