Modelling turbulent premixed combustion in the intermediate steady propagation regime [PDF]

open access: yes, 1999
Numerical simulation and comparison with standard experimental data of turbulent premixed combustion occurring at large Reynolds and moderately large Damkohler numbers (a situation which is typical in industrial burners) have been presented.

Numerical investigation of high-pressure combustion in rocket engines using Flamelet/Progress-variable models

open access: yes, 2014
The present paper deals with the numerical study of high pressure LOx/H2 or LOx/hydrocarbon combustion for propulsion systems. The present research effort is driven by the continued interest in achieving low cost, reliable access to space and more ...

Orbital and Electrical Dual Function of Polymer Intercalant for Promoting NH4+ Storage in Vanadium Oxide Anode

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
The impact of polyaniline insertion on the atomic orbitals and electronic structure of vanadium oxide anode is systematically investigated for the first time. The electrode exhibits an outstanding capacity and unprecedent long‐term cycling life, owing to the electron transition to the V 3dxy state and the enhanced diffusion kinetics.

Role of acoustics in flame/vortex interactions [PDF]

open access: yes
The role of acoustics in flame/vortex interactions is examined via asymptotic analysis and numerical simulation. The model consists of a one-step, irreversible Arrhenius reaction between initially unmixed species occupying adjacent half-planes which are ...

Adaptive multiresolution schemes with local time stepping for two-dimensional degenerate reaction-diffusion systems

open access: yes, 2008
We present a fully adaptive multiresolution scheme for spatially two-dimensional, possibly degenerate reaction-diffusion systems, focusing on combustion models and models of pattern formation and chemotaxis in mathematical biology.

Shedding Light on Common Misinterpretations in Photocatalyst Characterization

open access: yesAdvanced Energy Materials, EarlyView.
For heterogeneous semiconductor‐based photocatalysts, Marschall et al. highlight common misconceptions in material synthesis, characterization, and performance evaluation, together with detailed explanations on how to avoid them. The guidelines thus presented can help to improve reporting of photocatalyst performance in environmental applications, such

Impact of low-pressure conditions on flame width and volume of buoyant methane laminar diffusion flames

open access: yesCase Studies in Thermal Engineering
In this work, an experimental investigation of the main morphological parameters of buoyant methane laminar diffusion flames, including flame width and flame volume, is carried out under various sub-pressures (20-100 kPa).

An SMLD joint PDF model for turbulent non-premixed combustion using the flamelet progress-variable approach

open access: yes, 2015
This paper provides an improved flamelet/progress variable (FPV) model for the simulation of turbulent combustion, employing the statistically most likely distribution (SMLD) approach for the joint probability density function (PDF) of the mixture ...
