对同心环碟片填料旋转床在气液两相沿径向逆流条件下，进行了水－空气压降测量，推导出压降与操作工况的关联式。测量结果表明，该关联式与实测值吻合较好．研究发现在旋转床压降分析中必须考虑科氏力的影响，在总压降中摩擦阻力所引起的压降占主要部分．
Water-air pressure drop measurement was carried out on concentric ring disc packing rotating bed under the radial countercurrent condition of gas-liquid two-phase, and the correlation between pressure drop and operating conditions was deduced. The measurement results show that the correlation is in good agreement with the measured value. The study found that the influence of Coriolis force must be taken into account in the analysis of the pressure drop across the rotating bed, where the pressure drop caused by the frictional resistance is the major part.
