Overall volumetric mass transfer coefficient in a modified reversed flow jet loop bioreactor with low density particles

Abstract

Experiments were conducted using glass beads and Hr m low-density particles such as polyurethane and polystyrene which are comparable to bioparticles found in biological applications to evaluate the overall volumetric mass transfer KL m scoefficient (KLa) List of symbols

Impact of nozzle operation on mass transfer in jet aerated loop reactors. Characterization and comparison to an aerated stirred tank reactor

“…4A, Section 2.4). For the JLR the absolute values of the obtained k L a dyn values (k L a dyn (P L /V, u g ) fit to the results obtained by correlation published by Jamshidi et al [37] and Prasad and Ramanujam [36] (Eq. (9)).…”

“…For the JLR the k L a value was correlated using the Sherwood number (Sh), the respective diffusion coefficient (D AB ) and a length scale expressed as diameter (D R ) of the section available for co-current flow of gas and liquid [36,37].…”
