采用相位多普勒颗粒测速仪 (PDPA)对旋流数为 1 0的轴向和切向进风的圆柱形旋风筒内强旋湍流气粒两相流动进行了测量研究 ,并与旋流数为 0 47、 1 5和 2 0 8的实验结果进行了对比分析 ,指出了旋流数变化对两相流场及两相湍流特性的影响 .
The phase rotation of the strongly swirling turbulent particle-gas two-phase flow in the axial and tangential inlet cyclones with phase-Doppler velocimetry (PDPA) was measured and compared with the number of swirl The experimental results of 0 47, 1 5 and 2 0 8 are compared and analyzed, and the influence of the change of the number of swirl on the characteristics of two-phase flow field and two-phase turbulence is pointed out.
