使用 MIKE 3 装置研究了颗粒尺寸对铝尘云最小点火能 (MIE) 的影响。结果表明，MIE 值随着颗粒尺寸的增大而减小。对于微米尺寸和更大的铝颗粒，dp3 对 MIE 的依赖性与理论相关性一致。当粒径大约 <10 μm 时，可以观察到 30 nm <dp< 10 μm 时 dp0.5 与 MIE 的相关性。这项研究证实了 d 对铝尘云 MIE 依赖性的观察结果：MIE∼dp3 表示扩散，MIE∼dp0.5 表示动力学控制状态。
The effect of particle size on the minimum ignition energy (MIE) of aluminum dust clouds is investigated using a MIKE 3 apparatus. The results show that the MIE values decrease with particle sizedp. The dependence ofdp3on the MIE for micron-sized and larger aluminum particles is in agreement with the theoretical correlation. When the particle size is approximately <10 μm, the dependence ofdp0.5on the MIE for 30 nm <dp< 10 μm can be observed. This study confirms the observations of the dependence ofdpon the MIE of aluminum dust clouds: MIE∼dp3for diffusion- and MIE∼dp0.5for kinetic-controlled regimes.
