Abstract
Vortex bursting has been investigated by many researchers for analyzing the turbulent flame structure and developing the new combustion system in recent years. But few research for vortex bursting in the high-pressure such as turbulent flames in internal-combustion engine is investigated. In this report, flame visualization of spark ignited premixed flame in a rotational cylindrical closed cuvette is made for initial pressure condition of 1〜5atm, and rotation condition of 0, 4800, 9000, 15000rpm. The initial pressure conditions are set to be as same as that of micro gas-turbine combustion.
