Unsteady-state Hydrodynamics in Trickle-bed Reactors

The standard deviation maps have been linearly interpolated to the same in-plane spatial resolution as the high resolution data. Images are shown for a constant gas velocity of 112 mm s and the data were recorded as a function of decreasing liquid velocity. The liquid velocities are (a) 2.8, (b) 3.7, (c) 6.1 and (d) 7.6 mm s-1.
