The bubbling process had three different flow regimes with the increase of gas flow rate:periodic bubbling regime,chaotic bubbling regime and jetting .

Numerical simulation of pollutants convection diffusion in coastwise recirculation zone;

Up till now,the key problem of how to put the oil moisture into the recirculation zone has been solved,and the appropriate value of the main parameters were obtained through the experiments.

The PIV technology was applied to study flow fields of the flame holder wake,which reveals that the good combustion characteristics depend on the recirculation zone structure of slit flame holder and the particular vortex shedding patterns.
