Trickle bed hydrodynamics and flow regime transition at elevated temperature for a Newtonian and a non-Newtonian liquid

Hydrodynamics and Kinetics of Phenols Removal from Industrial Wastewater in a Trickle Bed Reactor (Part I: Hydrodynamic Study)

“…7 also shows a comparison between the present work and the data of. 22 The values of axial dispersion found with the work of 22 are lower than our experimental data. One possible cause for the observed mismatch is the differences in the geometric variables of the experimental setups.…”

“…The results of the present work are in agreement with findings of. 22,25 Fig. 6 shows the comparison between the present work with data of.…”

Hydrodynamics of cocurrent two‐phase flows in slanted porous media—Modulation of pulse flow via bed obliquity

“…35,36 For inclined configurations, only at low superficial gas velocities (u G ¼ 0.154 m/s) that pulse velocity was affected by inclination angle following a threshold process. There exists a critical angle below which pulse velocity was indifferent to inclination and above which pulse velocity decreased with increasing inclination angle.…”

Slow‐mode induced pulsing in trickle‐bed reactors at elevated temperature

“…The gas was then released from the separator to the atmosphere via a calibrated flowmeter, while the liquid was recirculated back into the feed tank. For the measurements of induced pulsing flow characteristics, two electrical conductivity probes of the design adopted by Tsochatzidis and Karabelas 17 and Boelhouwer et al 2 and described in more detail elsewhere, 15 were placed in the middle of the reactor with a separation distance of 245 mm. Each probe, consisting of two ring electrodes 1 mm thick and 30 mm apart, was connected to a lock-in amplifier to acquire the output signal.…”

“…Details of the experimental setup were given elsewhere. 15 Nonporous glass beads with a diameter of 3 mm were used as the packing, yielding bed porosity equal to 0.39.…”
