Interfacial area for packet towers

Abstract

A model for predicting the values of interfacial area from liquid hold-up is presented for various and shapes of packings generally employed in laboratorious and industry. The value of the liquld hold- up has been evaluated from the vertical surface model and random angle model proposed by Davidson. The calculated values are in good agreement with the reported values of wetted area and interfacial area (maximum value) obtained by the chemical method. It is observed that with the increase in size of the packing, the packing behaves as a vertical surface. The reported values of interfacial area for physical absorption and evaporation are blw compared with the calculated values.
