The experimental results show that it has a higher total pressure recovery coefficient and a narrow lean blowoff limit.

A uniform and a local rich fueling designs of dome have been made,and tests for comparing the influence of the two designs on combustor lean ignition and blowout limits have also been carried out in an experimental annular combustor.

The algorithms to determine the flame boundary and compute the flame length are designed based on the extracted image.

The assumption of unity Lewis number in the flamelet model of turbulent combustion is examined and the influence of differential diffusion and radiation on the flamelet structure, nitric oxide emission and extinction limit is investigated.

In a pilot scale reverse flow reactor with a liter of catalyst, catalytic combustion of typical industrial waste gas contaminated with volatile aromatic compounds (VOC) was systematically investigated, and the "temperature run-away"in the case of too high feed concentration and the "extinction of reactor" in the case of low feed concentration were observed.

Using the digital image processing technique and the laser tomography technique, a novel approach based on the turbulent intermittence was proposed here to describe the extinction process of turbulent flame.
