Liquid‐Phase mass transfer coefficients in bioreactors
Biotechnology and Bioengineering, 1992AbstractLiquid‐phase mass transfer coefficient in bioreactors have been examined. A theoretical model based on the surface renewal concept has been devloped. The predicted liquid‐phase mass transfer coefficients are compared with the experimental data for a mycelial fermentation broth (Chaetomium cellulolyticum) and model media (carboxymethyl cellulose)

Mass Transfer Coefficient: Comparison between Methods
Peritoneal Dialysis International: Journal of the International Society for Peritoneal Dialysis, 1993The mass transfer area coefficient (MTC) is the best parameter for solute transport evaluation in continuous ambulatory peritoneal dialysis (CAPD) patients. We compared three simplified MTC methods (calculated according Garred, Krediet, or Lindholm) and the peritoneal equilibration test (PET) (Twardowskl) to complex MTC (MTCX ...

Measurement of local mass transfer coefficient in biofilms
Biotechnology and Bioengineering, 1995AbstractLocal mass transfer rates for an electrochemically formed microsink in an aerobic biofilm was measured by a mobile microelectrode using limiting current technique. Mass transfer coefficients varied both horizontally and vertically in the biofilm.

Mass transfer characteristics and overall mass transfer coefficient in the ozone contactor
Korean Journal of Chemical Engineering, 2005The overall mass transfer coefficient kLa,F in the flow characteristics was determined by the measurement of the diffusivity of ozone, density of aqueous solution, and viscosity. However, the measured values kLa,F in the range of 0.0096–0.0622 min-1 show large changes in hydraulic retention time, and the dissolved ...

Journal of Food Engineering, 2006
Increasing trade of ready to eat foods such as cookies highlights an interest in quality defects (cracking, checking due to non-homogenous moisture distribution) during baking. The most important parameter resulting in adverse quality changes is non-homogenous moisture distribution due to diffusion and external convective mass transfer coefficient.

Mass and heat transfer coefficients
2013In a blood oxygenator, the blood spends approximately 2 s passing through the device. Estimate a minimum value for h m , the mass transfer coefficient characterizing oxygen transport from the plasma to the inside of a red blood cell (RBC), such that the RBCs are completely (i.e.

A Correlation for Mass Transfer Coefficients in Elbows
CORROSION 1998, 1998Abstract Mass transfer can have a significant effect on corrosion rates depending on the solution chemistry and flow conditions. Therefore, knowledge of the distribution of mass transfer coefficients along the flow geometry can be useful in determining the severity of corrosion rates in situations where mass transfer is a factor. In this

Mass transfer coefficients in mixer—settlers
Journal of Applied Chemistry and Biotechnology, 1973AbstractMass transfer coefficients have been determined for transfer into a highly viscous phase in a stirred tank involving high Schmidt numbers. The results have been used to compute mass transfer coefficients in the extraction of free fatty acids from oils using alcohol and show good agreement with experimental results.

Mass‐transfer coefficients in washcoated monoliths
AIChE Journal, 2004AbstractThe asymptotic mass‐transfer coefficients are determined in washcoated monoliths of various geometric shapes by solving the convection–diffusion equation in the fluid phase coupled with the diffusion–reaction equation in the washcoat. The dependency of the asymptotic Sherwood number (Sh∞) on washcoat properties (relative effective washcoat ...
