高圧環境における燃焼現象

抄録

An overview of fundamental and principal mechanism of high-pressure combustion and some examples of combustion phenomena in a high-pressure environment were presented. High pressure combustion is effective for improving thermal efficiency of internal combustion engines, enhancing heat release in a unit volume of high-load combustors, as well as increasing product yields from chemical reactors. The effects of pressure concern detail chemistry, gas-solid reaction, boundary layer thickness, structure of turbulence, decreasing laminar burning velocity, enhancing soot formation, etc. Combustion diagnostics for high pressure flames is also challenging theme. High pressure combustion gives us various subjects not only of scientific interests but also development of advanced and efficient combustion systems.
