Implementation of the Scalar Dissipation Rate in the REDIM Concept and its Validation for the Piloted Non-Premixed Turbulent Jet Flames

Eurasian Chemico-Technological Journal, 2021
In order to address the impact of the concentration gradients on the chemistry – turbulence interaction in turbulent flames, the REDIM reduced chemistry is constructed incorporating the scalar dissipation rate, which is a key quantity describing the ...

Functionalized Organic Lithium Salt Enables Flexible Solid‐State Electrolytes With Dual‐Ion Channels for Safe Li Metal Batteries

Carbon Energy, EarlyView.
Here, we design a flexible and non‐flammable solid‐state electrolyte with hierarchical dual‐ion conductive channels. The engineered electrolyte combines continuous organic conductive‐phase pathways for fast bulk Li+ transport and dynamic polymer networks for interfacial ion hopping, achieving unprecedented room temperature conductivity (> 1 mS cm−1 ...

Large Eddy Simulation of a Turbulent Nonpremixed Jet Flame Using a Finite-Rate Chemistry Model [PDF]

, 2009
Large eddy simulation (LES) is conducted of a turbulent piloted nonpremixed methane jet flame. This flame has been studied experimentally at Sandia National Laboratories. The subgrid scale (SGS) closure in LES is based on the scalar filtered mass density

Reconstruction Method of 3D Turbulent Flames by Background-Oriented Schlieren Tomography and Analysis of Time Asynchrony

Fire, 2023
Background-oriented Schlieren tomography (BOST) is widely used for 3D reconstruction of turbulent flames. Two major concerns are associated with 3D reconstruction. One is the time asynchrony within the data acquisition of the high-speed camera. The other

Global and Detailed Calculation of Tube Wall Temperature in a Process Furnace Steam Superheater

Chemie Ingenieur Technik, EarlyView.
This study presents a comparison between an iterative global model and multiple approaches to a new non‐iterative model with the purpose of predicting tube wall temperature of a superheater. The results show that the non‐iterative method achieves sufficient accuracy while improving the prediction of local temperature distribution and better ...

Statistical analysis of the velocity and scalar fields in reacting turbulent wall-jets

, 2015
The concept of local isotropy in a chemically reacting turbulent wall-jet flow is addressed using direct numerical simulation (DNS) data. Different DNS databases with isothermal and exothermic reactions are examined.

The Effect of Jet-Induced Disturbances on the Flame Characteristics of Hydrogen–Air Mixtures

Fire
To mitigate explosion hazards arising from hydrogen leakage and subsequent mixing with air, the injection of inert gases can substantially diminish explosion risk. However, prevailing research has predominantly characterized inert gas dilution effects on

Protocol for Reconstituting Adaptor‐Mediated Activation of Full‐Length Kinesin‐1

Cytoskeleton, EarlyView.
ABSTRACT Kinesin‐1 is a member of the kinesin superfamily that plays an essential role in intracellular cargo transport. In the absence of cargo, Kinesin‐1 exhibits low motor activity due to autoinhibition. Multiple studies have demonstrated that adaptor proteins, which link cargos to Kinesin‐1, can activate Kinesin‐1 by releasing the autoinhibition ...
