Experimental Investigation of Microbubble Evolution in the Liquivac Multiphase Flow Pump
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT This paper aims to experimentally investigate the mechanisms of microbubble characteristics evolution within an axial pump. The findings will aid in assessing the pump performance by identifying the range of bubble sizes and comparing them with the threshold size (< 300 μm). This study also provides evidence supporting the use of such pumps as

Automated Process Optimization in a Novel Triple Shaft Mixer with Adaptive Mixing Modes
Chemie Ingenieur Technik, EarlyView.A novel multi‐purpose mixer with adjustable blade angle and a coaxial stirrer is developed, providing three degrees of freedom. An optimization strategy is integrated to autonomously identify optimal operating conditions through automated tests. The current draw of the main stirrer serves as the optimization criterion, while stirrer speeds, directions,
