Gas holdup in a reciprocating plate bioreactor: Non-Newtonian - liquid phase [PDF]
Hemijska Industrija, 2002 The gas holdup was studied in non-newtonian liquids in a gas-liquid and gas-liquid-solid reciprocating plate bioreactor. Aqueous solutions of carboxy methyl cellulose (CMC; Lucel, Lučane, Yugoslavia) of different degrees of polymerization (PP 200 and PP ...

Hydrodynamics in a cocurrent gas-liquid trickle bed at elevated pressures [PDF]
, 1991 Data on design and operation of trickle beds at elevated pressures are scarce. In this study the influence of the gas density on the liquid holdup, the pressure drop, and the transition between trickle and pulse flow has been investigated in a tricklebed
