摘　　要：分析了闭式循环柴油机(CCD)旋转床CO2吸收器内气液流动特点,建立了流经碟片填料旋转床吸收器气体压降计算模型。通过实验及编程计算,得到了气体压降数学模型中实验关联系数值。经不同工况下气体压力降模型计算值与实验值对比,表明两者相对误差小于15%,可用于实际CCD系统旋转床CO2吸收器的优化设计。The models of gas pressure drop in the rotating packed-bed CO_2 absorber of closed cycle diesel (CCD) system were established based on analyzing gas-liquid flow characteristics in the absorber. Using the experimental data and the calculation program, the experimental correlation coefficients of the models of gas pressure drop were obtained. The contrast between the calculated data and the experimental data indicates that the former is quite fit with the latter and the relative error is less than 15%. So, these models can be used in the optimization design for rotating packed-bed CO_2 absorber of actual CCD system.
