Abstract

The gas-liquid mass transfer volumetric coefficient k_Lα for an EGSTAR agitator, which has been practically used as a bioreactor, is measured. The effect of geometries (i.e., hole fraction, pitched paddle width, draft tube height) on k_Lα is clarified experimentally. k_Lα depends only on the power consumption per unit volume (P_av+P_gv), regardless of the hole fraction and the pitched paddle width in the power region of (P_av+P_gv) =0.54.0 kW/m³. As the draft tube height of EGSTAR agitator is lower, the power consumption at the transition point from bubbling controlling to agitation controlling is lower.
