Tube-side mass transfer for hollow fibre membrane contactors operated in the low Graetz range
Transformation of the tube-side mass transfer coefficient derived in hollow fibre membrane contactors (HFMC) of different characteristic length scales (equivalent diameter and fibre length) has been studied when operated in the low Graetz range (Gz<10). Within the low Gz range, mass transfer is generally described by the Graetz problem (Sh=3.67) which assumes that the concentration profile comp...
متن کاملDrag coefficient and strouhal number analysis of a rectangular probe in a two-phase cross flow
In some case of laboratory and industrial applications, various kind of measurement instruments must be placed in a conduit, in which multiphase fluid flows. Vortex shedding for any immersed body in flow field is created with a frequency, which according to flow conditions such as flow rates, geometry of body, etc. may be constant or variable. Failure may happen, if this frequency is close to o...
متن کاملTurbulent Events and Gas-Side Mass Transfer Coefficients in a Wavy Air-Water Stratified Flow
Turbulence structure on the gas side of a wavy stratified flow was experimentally investigated in a near horizontal 18.7 cm (H) 10 cm (W) 5.5m (L) rectangular duct.By applying the Variable Interval Time Averaging (VITA) technique to the hot wire anemometer measurements frequency of occurrence of turbulent events were detected near the air-water interface. Experimental results showed that fr...
متن کاملBiological treatment and thickening with a hollow fibre membrane bioreactor.
Aerobic operation of an immersed hollow fibre membrane bioreactor, treating municipal wastewater supplemented with molasses solution, has been studied across mixed liquor suspended solids (MLSS) concentrations between 8 and 32 g L(-1), the higher concentrations being normally associated with thickening operations. Only a marginal loss in membrane permeability was noted between 8 and 18 g L(-1) ...
متن کاملHollow fibre membrane arrays for CO2 delivery in microalgae photobioreactors
Microalgae can serve as a carbon sink for CO2 sequestration and as a feedstock for liquid biofuel production. Methods for microalgal biomass and biofuel cultivation are progressing, but are still limited in the efficiency of light delivery and gas exchange within cultures. Specifically, current gas exchange methods are very energy intensive since they rely on mixing algal cultures at high flow ...
