Figures & Tables

Figure 1

Picture of the membrane.

Figure 2

Geometric model of the bubble column with membrane module.

Figure 3

Geometric model of the cell, created with a CAD modeler. (a – basic volume of the single-cell; b- the added volume of the fluid in front and behind the membrane)

Figure 4

Geometrical model of the fluid part for a different number of single cells.

Figure 5

The permeability of the membrane by simulation of one, two and four cells from the representative area of the membrane structure and for fluids with different viscosity.

Figure 6

The fluid flow depending on the viscosity.

Figure 7

Water volume fraction (a), gas holdup (b), water velocity (c) and air velocity (d) in bubble column at the numerical solution with superficial gas velocity 0,5 m/s and bubble diameter 3 mm.
