Experiment and Numerical Simulation on the Gas Flow Field of the Swirl Pulverized Coal-Oxygen Burner

Accorhing to the analogue theory, a cold experimental model for simulating the swirl pulverized coal-oxygen burner used in the industrial test was designed and established.
By one dimension LDV, the distribution of axial velocity in the swirling field given was measured. Depending upon the measurement datum by the LDV, the mathematic model for showing the swirling field given was developed, and the measurement value was in good agreement with the calculation value of the model. It is considered that the approch was more satifactory than other methods at present as the axial velocity distribution in the reverse flow area was shown by cosine function. Hence, the some problems on the gas dynamics of the swirling field was also discussed in this paper.
