Synthesis of uniform core‐shell calcium hydroxide‐calcium carbonate biocidal particles via encapsulation into dry ice

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Synthesis of core‐shell calcium hydroxide‐calcium carbonate biocidal particles via encapsulation into dry ice. Abstract This study introduces a novel synthesis method for core‐shell calcium hydroxide‐calcium carbonate (CSCC) biocidal particles by inducing a phase change in liquid CO2$$ {\mathrm{CO}}_2 $$, thereby coating CaOH2$$ \mathrm{Ca}{\left ...

Impact of slug length in gas–liquid two‐phase flow on the structural stress characteristics of horizontal rigid pipelines

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Data collection and processing of slug length in two‐phase flow‐induced stress analysis. Abstract The intermittent passage of liquid slugs and gas pockets in slug flow generates substantial cyclic stress damage to piping systems and their supports. This issue poses significant challenges to the various industries in which this flow pattern is present ...

Laboratory‐Based Time‐Resolved In Situ X‐Ray Absorption Spectroscopy for Tracking Transformations of Working Electrocatalysts

open access: yesChemistry–Methods, EarlyView.
The experimental setup presented in this work combining laboratory‐based X‐ray absorption spectroscopy with an electrochemical reactor advances the fundamental understanding of electrocatalysts at extended time scales. By the example of the electrochemical reduction of CO2, the parameters are discussed that are relevant for optimizing the system to ...

Continuous Flow Block Copolymer Nanoaggregate Synthesis and Their Flow Dialysis Purification

open access: yesChemistry–Methods, EarlyView.
This work details the methodology for the synthesis of block copolymer nanoparticles through continuous flow self‐assembly and purification via flow dialysis. Nanoaggregates are formed by mixing block copolymer solutions in THF with water, followed by dialysis to eliminate excess solvent.

Turbulent/Turbulent Entrainment

2021
The interfacial region between two bodies of turbulent fluid was investigated through simultaneous particle image velocimetry (PIV) and planar laser induced fluorescence (PLIF) experiments in the far wake of a circular cylinder. Interface conditioned plots of enstrophy revealed the existence of a turbulent/turbulent interface (TTI) where the enstrophy ...

Development of a turbulence closure model for geophysical fluid problems

, 1982
Applications of second-moment turbulent closure hypotheses to geophysical fluid problems have developed rapidly since 1973, when genuine predictive skill in coping with the effects of stratification was demonstrated. The purpose here is to synthesize and

Reassessment of the scale-determining equation for advanced turbulence models

, 1988
A comprehensive and critical review of closure approximations for two-equation turbulence models has been made. Particular attention has focused on the scale-determining equation in an attempt to find the optimum choice of dependent variable and closure ...
