superficial velocity
1.Liquid circulation rate and gas holdup in an ALR were experimentally investigated aschanging with the superficial gas velocity for the system of air-water.
2.The author of the paper preliminarily inquires into the effect of gas velocity, superficial liquid velocity, static bed height, density of packing ball, and the area of a single packing ball surface on the pressure drop across the bed, height of bed expansion, outlet co_2-content, desorption efficiency, and the mass transfer coefficient K_L.
3.The influence operating conditions on the hydrodynamics and mass transfer performance of ALR, including superficial gas velocity, the properties and level of liquid phase, the properties and content of solid phase, as well as electrolyte and magnetic field, are discussed.
4.Furthermore, measurements of particle rotation in transition area at a height of 0.98m above the distributor plates in a cold CFB riser were carried out and the average particle rotational speed is found to be as much as 280r/s at superficial gas velocity Vg=3.5m/s and particle diameter dp=450-850μm .
5.Velocity enhancement with IPC was similar between groups and the superficial femoral and popliteal veins.
