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

Thermal Calculations for Co‐Firing of Hydrogen/Ammonia and Coal in 660‐MW Coal‐Fired Boilers
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT To achieve a clean energy transition under the dual carbon goals, blending hydrogen/ammonia into pulverized coal boilers represents a key technological pathway. Different hydrogen/ammonia co‐firing ratios (5%–50%) are investigated for their impact on the thermodynamic characteristics of 660‐MW supercritical boiler at 100% and 20% boiler ...

Secondary vortices in swirling flow [PDF]
, 2010 Twisted tapes are used to induce swirling flow and improve mixing. The flow induced by a 180 degree twisted tape with length (pitch) 60 mm and diameter 25.4 mm in a circular pipe was investigated using Laser Doppler Velocimetry (LDV) measurements ...

Biotechnology Progress, EarlyView.This work describes the development of human hemoglobin nanoparticles using an anti‐solvent precipitation synthesis method as a potential next generation hemoglobin‐based oxygen carrier. The hemoglobin nanoparticles are uniform in size and shape, hemocompatible, stable at various storage conditions, and demonstrate a scalable synthesis technique ...

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.

Numerical Assessment of Novel Helical/Spiral Grafts with Improved Hemodynamics for Distal Graft Anastomoses. [PDF]
PLoS ONE, 2016 In the present work, numerical simulations were conducted for a typical end-to-side distal graft anastomosis to assess the effects of inducing secondary flow, which is believed to remove unfavourable flow environment.

Kinematic Alpha Tensors and dynamo mechanisms in a von Karman swirling flow [PDF]
, 2012 We provide experimental and numerical evidence of in-blades vortices in the von Karman swirling flow. We estimate the associated kinematic α-effect tensor and show that it is compatible with recent models of the von Karman Sodium (VKS) dynamo. We further

Numerical modeling of flows with flow swirling [PDF]
Computer Research and Modeling, 2013 This paper is devoted to investigation of the swirl flows. Such flows are widely used in various industrial processes. Swirl flows can be accompanied by time-dependent effects, for example, precession of the vortex core. In turn, the large-scale fluctuations due to the precession of the vortex can cause damage of structures and reduce of equipment ...

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).
