Effect of Gas Distributor on Gas Holdup in Fiber Suspensions
Volume 3, 2004 Two different aeration plates are used to study their effect on gas holdup and flow regime transition in fiber suspensions. Two gas distributors with different open areas (A = 0.57% and 2.14%) and the same orifice diameter (do = 1 mm) are used, and experiments are performed using three different Rayon fiber lengths (L = 3, 6, and 12 mm) over a range of

Gas Holdup Behavior in Nylon Fiber Suspensions
Industrial & Engineering Chemistry Research, 2004 The gas holdup behavior in a nylon fiber suspension with various fiber lengths (L = 2, 3, and 6 mm) is investigated. Experiments are performed over a range of superficial gas velocities (U g ≤ 18 cm/s) and a range of fiber mass fractions (0 ≤ C ≤ 1.8%) in a 15.24-cm-diameter semibatch bubble column.

Gas Holdup in Opaque Cellulose Fiber Slurries
Volume 1: Symposia, Parts A and B, 2005 Three different cellulose fiber types are used to study their effect on gas holdup and flow regime transition in a 10.2 cm semi-batch bubble column. The three natural fiber types include bleached softwood chemical pulp (softwood), bleached hardwood chemical pulp (hardwood), and bleached softwood chemithermomechanical pulp (BCTMP).

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 ...
