Effect of surfactauts on gas hold-up in baffed column reactor

Investigation of Gas Hold-up and Bubble Behavior in a Split-Cylinder Airlift Reactor: Pseudo-Plastic Non-Newtonian Fluids

Gas Hold-Up in a Reactor with Dual System of Impellers*

Results of experimental studies of gas hold-up in a liquid stirred mechanically in a reactor, which was equipped with double stirrers on a common shaft, are presented. Coalescing and noncoalescing gas—liquid systems were tested. The measurements were carried out for aqueous solutions of glucose and glucose sirup, as well as for different configurations of dual high-speed impellers. Stirred tank...

Gas hold-up and bubble diameters in a gassed oscillatory ba'ed column

In this paper attempts are made to address how bubble behaviour in a batch oscillatory ba'ed column (OBC) contributes to the overall measured enhancement in mass transfer. A CCD camera is used to measure the bubble size distribution and the gas hold-up in the OBC. The experimental results of Sauter mean diameter and gas hold-up are correlated as a function of the power dissipation and super5cia...

the effect of e-64 on the developmental competence of sheep cocs during in vitro maturation

in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
