Abstract

The effects of the viscosity and surface tension on the axial dispersion and liq. holdup was investigated in a 0.3-m-diam. packed column with countercurrent gas-liq. flow. The axial dispersion appeared to be independent of the viscosity and surface tension. The traditional complex form of correlating Peclet nos. as a function of the interstitial Reynolds and Galileo nos. may be replaced by a much simpler form contg. only the Froude no. as a correlating variable for the liq. phase. The axial dispersion depended slightly on the gas flow rate. Differences in axial dispersion and holdup were obsd. as a function of the radial position. [on SciFinder (R)]
