Influence of drag closures and inlet conditions on bubble dynamics and flow behavior inside a bubble column

Engineering Applications of Computational Fluid Mechanics, 2017
In this paper, the hydrodynamics of a bubble column is investigated numerically using the discrete bubble model, which tracks the dispersed bubbles individually in a liquid column.

The epithelial barrier theory proposes a comprehensive explanation for the origins of allergic and other chronic noncommunicable diseases

FEBS Letters, EarlyView.
Exposure to common noxious agents (1), including allergens, pollutants, and micro‐nanoplastics, can cause epithelial barrier damage (2) in our body's protective linings. This may trigger an immune response to our microbiome (3). The epithelial barrier theory explains how this process can lead to chronic noncommunicable diseases (4) affecting organs ...

Recent increases in tropical cyclone intensification rates

Nature Communications, 2019
Tropical cyclones that rapidly intensify are associated with the highest forecast errors and the strongest storms. This study shows that the proportion of tropical cyclones that rapidly intensify recently increased in the Atlantic basin, and that this ...

Explicit Prediction of Continental Convection in a Skillful Variable‐Resolution Global Model

Journal of Advances in Modeling Earth Systems, 2019
We present a new global‐to‐regional model, cfvGFS, able to explicitly (without parameterization) represent convection over part of the Earth. This model couples the Geophysical Fluid Dynamics Laboratory Finite‐Volume Cubed‐Sphere Dynamical Core (FV3) to ...

Energy Price as an Input to Fuzzy Wastewater Level Control in Pump Storage Operation

IEEE Access, 2023
This paper presents a novel control strategy for pumps in storage tanks that accounts for fluctuations in energy prices. Storage tanks are commonly used in industrial and commercial applications to store and transport large quantities of liquids or gases.

Fluid Dynamics of Bacterial Turbulence [PDF]

Physical Review Letters, 2013
Self-sustained turbulent structures have been observed in a wide range of living fluids, yet no quantitative theory exists to explain their properties. We report experiments on active turbulence in highly concentrated 3D suspensions of Bacillus subtilis and compare them with a minimal fourth-order vector-field theory for incompressible bacterial ...

Exploring lipid diversity and minimalism to define membrane requirements for synthetic cells

FEBS Letters, EarlyView.
Designing the lipid membrane of synthetic cells is a complex task, in which its various roles (among them solute transport, membrane protein support, and self‐replication) should all be integrated. In this review, we report the latest top‐down and bottom‐up advances and discuss compatibility and complexity issues of current engineering approaches ...
