摘要：

Flame behavior and heat transfer characteristics are investigated by conducting three dimensional direct numerical simulation (DNS) of turbulent hydrogen-air premixed flames in a constant volume vessel at relatively high Reynolds number with a detailed kinetic mechanism and temperature dependence of the transport and thermal properties. Time developments of the mean turbulent burning velocity, the flame surface area and the Reynolds number based on the Taylor micro scale with the internal pressure rise are evaluated. Effects of pressure increase during combustion on turbulent flow field and wall heat flux are investigated and compared with the results from our previous study.
