Experimental Investigation of the Interaction between Rising Bubbles and Swirling Water Flow

International Journal of Chemical Engineering, 2014
This study experimentally investigates the interaction between rising bubbles and swirling water flow imposed around the central (vertical) axis of a bubble plume in a cylindrical water tank. Small air bubbles are successively released from the bottom of

Highly Potent Fluorogenic Ligands for Triplex DNA: 5‐Substituted 2‐(Naphthalen‐2‐yl)‐4H‐Chromen‐4‐Ones

Chemistry – A European Journal, EarlyView.
5‐Substituted 2‐(naphthalen‐2‐yl)‐4H‐chromen‐4‐ones are reported as a novel class of highly potent and selective triplex DNA ligands. These ligands induce triplex formation at submicromolar concentrations and inhibit enzymatic activity via ligand‐mediated triplex formation.

Purification, Fluorescent Labeling, and Detyrosination of Mammalian Cell Tubulin for Biochemical Assays

Cytoskeleton, EarlyView.
ABSTRACT Microtubules play essential roles in numerous cellular processes. All microtubules are built from the protein tubulin, yet individual microtubules can differ spatially and temporally due to their tubulin isotype composition and post‐translational modifications (PTMs).

Study on Multi-Processing Vortex Core and Wall Shear Stress in Swirling Flow of a Guide-Vane Hydro-Cyclone for Agricultural Irrigation

Agriculture
To investigate the spatiotemporal dynamics and wall shear stress patterns of a PVC (precessing vortex core) within a bounded swirling flow for agricultural irrigation, LES (Large Eddy Simulation) simulations based on a guide-vane hydro-cyclone were ...

Study on the Addition of A Swirling Vane to Spark Ignition Engines Fueled by Gasoline and Gasoline-Ethanol

Automotive Experiences, 2023
Although the technology of fuel injection in motorcycles has reached ports and direct injection, motorcycles with carburetors are still used. In this research, the carburetor was modified by adding a swirling vane.

Stability of Viscous Three‐Dimensional Stratified Couette Flow via Dispersion and Mixing

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT This article explores the stability of stratified Couette flow in the viscous 3d$3d$ Boussinesq equations. In this system, mixing effects arise from the shearing background, and gravity acts as a restoring force leading to dispersive internal gravity waves.

Enhancement of Liquid-Solid Two-Phase Flow Through a Vertical Swirling Pipe

Journal of Applied Fluid Mechanics, 2020
In order to improve the transportation efficiency and safety of the vertical hydraulic transport pipe, a new type of pipeline transport system with helical blade is proposed in this paper. Based on CFD-DEM coupling method, the liquid-solid two-phase flow

Enhancing hydrogen evolution reaction by harnessing bubble dynamics regulation: Principles, methods, and outlook

Droplet, EarlyView.
Bubble dynamics pose critical bottlenecks to hydrogen evolution reaction efficiency, causing active site isolation, increased ohmic resistance, and concentration overpotential, especially at high current densities. This review comprehensively summarizes passive and active bubble manipulation strategies, elucidates their underlying principles, and ...

Influence of bluff-body and swirl on mixing and intermittency of jets [PDF]

, 2010
In this paper we present the modelled results of turbulence, scalar mixing and intermittency for three different basic fluid dynamical problems using large eddy simulation (LES). The modelled problems are a turbulent round jet, a bluff body stabilised
