摘要
提出了一个关于流化床中气泡周围乳化相结构的物理模型，分析了扰动信号在气固流化床中的传播规律及其对气泡稳定性的影响，得到了最大稳定气泡尺寸，并与相关的理论研究和实验结果进行了比较。
An in-depth investigation on the structure of the emulsion phase around a single risingbubble in a wide-sized gas-solid fluidized bed shows that there are three regions as accordingto the degree of the influence by the bubble, that is,the bubble rnembrane,the propagationand the inertia regions,respectively.The propagation of bubble-induced disturbance is stud-ied,with the regularity of the voidage variation and the maximum stable bubble size found.Acomparison of calculation results using the model with experimental data is made.
