在较宽的气速范围内，对常用的床层有效直径进行了实验和数值研究。这项工作的动机是欧拉方法对多相介质进行建模。在所进行的实验条件和Gidaspow阻力模型的条件下，所谓的模态有效直径Dmod与实验结果吻合得最好。对于较小的气体速度，对直径D32进行了修正，以使其与实验最吻合。
Theexperimental and numerical study of common used effective diameters for fluidized bed at a wide range of gas velocities was carried out. This work was motivated by Eulerian approach to modelling multiphase media. In the conditions of the experiments carried out and the Gidaspow drag model, the best agreement with the experiment was shown by the so-called modal effective diameter Dmod. For minor gas velocities, the diameter D32 was corrected in order to best coincide with the experiment.
