A New Methodology For Hydrodynamic Similarity In Bubble Columns, Ashfaq Shaikh, Muthanna H. Al-Dahhan

Chemical and Biochemical Engineering Faculty Research & Creative Works

Bubble Columns Are Widely Used in Chemical, Petrochemical, and Biochemical Industries for Various Processes Such as Alkylation, Oxidation, Chlorination, Wet Oxidation of Effluents, Etc. a New Hypothesis for Hydrodynamic Similarity that Can Be Subsequently Used for Scale-Up of Bubble Column Reactors Was Proposed. This Hypothesis Was Evaluated using Advanced Diagnostic Techniques. the Conditions of Similarity Where overall Gas Holdup and Radial Gas Holdup Profiles Were the Same, and Mismatch Where overall Gas Holdup Was the Same But Gas Holdup Radial Profiles Were Different, Were Identified. the Condition that Two Systems Must Operate in the Same Flow Regime to Be Hydrodynamically …
