Combustion, performance and emission were studied for DI diesel engine fuelled with DMM/diesel fuel blends for DMM content from 0 to 50%. Results showed that, for diesel engine with fuel supply system and combustion system unchanged, with increased DMM percentage, thermal efficiency slightly increases; smoke and CO emissions decrease, NOx remains almost unchanged while HC increases a little; fo...

Combustion-induced turbulence is studied in explosions of methane/air a steel sphere with optical access. Rms turbulent velocities, u', created by four peripheral variable speed fans, were measured Particle Image Velocimetry, PIV, which indicated near-uniform, isotropic turbulence, small mean velocities. The gaseous expansion near-spherical propagating flame generated radially outwards velocity...
