Imbibition in layered systems of packed beads
WitrynaThe packed-bed bioreactor was implemented in a stainless-steel column at 60 °C. The stainless-steel column was 25 cm in length with an inner diameter of 0.25 cm and packed with 1.3 g of Novozym ® 435. The upper and lower end of the column was layered with a 2 μm filter. The flow rates were controlled by a Hitachi Pump (L-2130, … Witryna14 gru 2024 · This option allows users to search by Publication, Volume and Page Selecting this option will search the current publication in context.

Imbibition in layered systems of packed beads
Did you know?
Witrynadeveloped a flow model for parallel layers of packed beads assum-ing that pressure in the two layers is same whenever same fluid is present in both the layers, while the fluid transfer between the lay-ers is assumed to be significant which occurs at the imbibing fluid front. However, their model neglects the viscosity of the resident fluid. WitrynaCalculated values for drainage, imbibition and tertiary recovery using SDS Input Data (Drainage) Value Units Pore Volume 14.38 ml Dead Volume 6 ml Flow rate 0.017 ml/sec OOIP 12 ml Irreducible water saturation 14.41 % Initial oil saturation 85.6 % Imbibition (Hard brine) Value Units Total vol. of oil recovered 8.8 ml OOIP 12 ml Recovery factor ...
WitrynaWe study imbibition of a wetting fluid into layers of packed beads and examine how variations of permeability in the flow direction affect the dynamics of imbibition. In the … Witrynaporous media show the imbibition at different times. The fluid exchange between the layers is represented by arrows in the snapshots. (a), (b) and (c) show the different …

WitrynaThe imbibition of a wetting fluid in a homogeneous porous medium follows the diffusion-like behavior described by Washburn. The impregnation of a two-layered porous medium by a wetting fluid due to capillary action has been previously described to have two fronts, one saturating the medium and the o …
