The influence of an electrochemically generated gas phase on the hydrodynamic
characteristics of a three-phase system has been examined. The two-phase
fluid, (gas-liquid), in which the liquid phase is the continuous one, flows
through a packed bed with glass spheres. The influence of the liquid
velocity was examined, as well as the gas velocity and particle diameter on
the pressure drop through the fixed bed. It was found that with increasing
liquid velocity (wl = 0.0162-0.03 m/s), the relative pressure drop decreases
through the fixed bed. With increasing current density, the pressure drop
increases, since greater gas quantities stay behind in the fixed bed.
Besides, it was found that with decreasing diameter of the glass particles,
the relative pressure drop also decreases. The relationship betweeen the
experimentally obtained friction factor and the Reynolds number was
established.
