摘　　要：对于Helmholz型脉动燃烧器在湍流情况下的燃烧,本文使用CFD方法进行了数值模拟,分析了燃烧室内、尾管内及出口处的气流压力、温度和速度脉动情况。数值计算结果表明,尾管出口处气流的速度脉动、热释放的脉动与燃烧室内的脉动频率一致。与尾管内相比,尾管出口处气流速度较快、温度较高,可分别适宜干燥不同的物料。For the combustion of Helmholz-type pulse burner in turbulent flow,the flow pressure,temperature and velocity in the combustion chamber,tail tube and outlet are analyzed.The numerical results indicate that the velocity and heat-released pulsations of the airflow at the tail tube outlet are consistent with the pulse frequency in the combustion chamber.Compared with the outlet and the tail tube,the air velocity is larger and the temperature is higher,which can be suitable for drying different materials.
