Viscoelastic Suppression of Gravity-Driven Counterflow Instability
, 2010 Attempts to achieve "top kill" of actively flowing oil wells by insertion of dense drilling "muds", i.e., slurries of dense minerals, from above will fail if the Kelvin-Helmholtz instability in the gravity-driven counterflow produces turbulence that ...

STRUCTURE OF TURBULENT VELOCITY AND BUOYANCY FLUCTUATIONS IN STRATIFIED TURBULENT SHEAR FLOW
Doboku Gakkai Ronbunshu, 1984 The effects of buoyancy on turbulence structure of a buoyant surface jet are investigated. Velocities and buoyancy fluctuations are simultaneously measured, and their statistic quantities are examined. Distributions of turbulence quantities are strongly affected by buoyancy. Their variations against the shear layer Richardson number can be explained in

Effect of cell retention techniques in Komagataella phaffii lab‐scale continuous processes
Biotechnology Progress, EarlyView.Abstract Perfusion technologies play a growing role in the implementation of continuous processes for biotherapeutics production in mammalian‐based manufacturing. However, their application to alternative production hosts is limited. Cell retention systems are of key importance for the efficiency of perfusion bioreactors.

An algebraic model for prediction of bypass and separation-induced transition in turbomachinery boundary layers [PDF]
, 2016 An algebraic intermittency model for bypass and separation-induced transition is presented. The model modifies the production terms of a k-omega turbulence model. It uses only local variables and is tuned for turbomachinery flows.

Experimental Parameter Study of the Factors Influencing Dry Dispersion Using Laser Diffraction
Chemie Ingenieur Technik, EarlyView.Laser light diffraction reveals how geometric, material and operational factors govern dry dispersion efficiency and particle size distribution of submicron cathode material. The findings provide guidance for systematic optimization of powder handling and subsequent processing steps.

A critical review of the experimental data for developed free turbulent shear layers [PDF]
Experimental shear layer data are reviewed and the results are compared to numerical predictions for three test cases. It was concluded from the study that many, if not most, of the apparent inconsistencies which exist in the interpretation of the ...

Uniform Gas Flow Distribution into Several Partial Flows under Consideration of Closable Outlets
Chemie Ingenieur Technik, EarlyView.The uniform distribution of a gas flow into several partial flows poses a challenge in various technical fields. This study presents a static flow distributor design that ensures an equal distribution of an inlet gas flow regardless of the flow rate and the number of open outlets.

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,
