Pressure Drop and liquid Holdup in Co-current Gas-Liquid Downflow of Air-CMC Solutions through Packed Beds

摘要

The present available experimental data on liquid holdup(735 data points)and pressure drop(863 data points)in co-current gas-liquid downflow through packed beds obtained using air-non-Newtonian(w = 0.2 %,0.5 %,0.8 % and 1 % CMC)solutions,were analyzed for their dependency on the system variables.Modified Reynolds number and Morton's number involving flow consistency index(k)and flow behavior index(n),along with other variables were used for the development of unified correlations to represent the available data.
