摘要/Abstract

摘要： Liquid phase axial mixing was measured with the tracer technique in a packed column with
innerdiameter of 0.15 m, in which the structured packing, Mellapak 350Y, was installed. Tap
water as the liquid phaseflowed down through the column and stagnant gas was at elevated
pressure ranging from atmospheric to 2.0 MPa.The model parameters of Bo andθ were
estimated with the least square method in the time domain. As liquid flowrate was
increased, the liquid axial mixing decreased. Under our experimental conditions, the effect
of pressure onBo number on single liquid phase was negligible, and eddy diffusion was
believed to be the primary cause of axialmixing in liquid phase.
