Experimental study of liquid spreading in structured packings

► Original measurements of liquid dispersion in a counter-current packed bed equipped with a modern high efficiency packing. ► Use of a high resolution gamma ray system. ► In a column of large size diameter with different fluids over a large range of operating conditions. ► A comparison of the experiments with a 2D model using a spread factor. ► Data are of high interest for further CFD modeling since they allow for the determination of closure laws of gas-liquid flow in packed beds.
