建立了悬浮粉尘燃烧过程的数学模型．应用此模型对小麦粉－空气混合物燃烧过程进行了数值模拟；其结果证实了火焰中的旋涡是由于粉尘浓度不均匀性造成了反应放热不均匀而引发的．这些结果对于理解颗粒粉尘层流燃烧特性是有益的．
The mathematical model of the combustion process of suspended dust was established. This model is used to simulate the combustion process of wheat flour-air mixture. The results show that the vortex in the flame is caused by the non-uniform exothermic reaction due to the non-uniformity of dust concentration. These results are useful for understanding the laminar burning behavior of particulate dust.
