Gas Hold-up and Pressure Drop in the Gas Fluidized Liquid-Solid Packed Bed
These experimental studies were carried out to make clear the effects of various factors, such as gas velocity U. surface of packing materials, and properties of the liquid, on the gas hold-up and pressure drop in the gas fluidized liquid-solid packed bed.
The results are summerized as follows:
1） Pressure drop in constant when the gas velocity is with in 10<U<24 [㎝/sec], and it becomes to decrease by increasing the gas velocity U, in the packed bed higher than 24 [㎝/sec].
2） Δh/Lf=1.73×10-2（NRe)-0.12(DT/DP)0.19(1-φ)-0.5
3） Lmax=6.13（DT/LO)DO-0.69DP-0.86
