Siloxane Decomposition and Clustering in Atmospheric Pressure Non‐Thermal Plasma Discharge

Plasma Processes and Polymers, Volume 23, Issue 6, June 2026.
Atmospheric‐pressure He/HMDSO plasmas convert HMDSO to PDMS deposits. At lower power, mass growth is suppressed, while small silicon‐containing fragments and hydrocarbon radicals dominate. Stable small hydrocarbons are formed at higher power, reflecting enhanced fragmentation and recombination pathways.

Two-Dimensional Tomographic Simultaneous Multi-Species Visualization—Part I: Experimental Methodology and Application to Laminar and Turbulent Flames

Energies, 2020
In recent years, the tomographic visualization of laminar and turbulent flames has received much attention due to the possibility of observing combustion processes on-line and with high temporal resolution.

Filtered density functions from direct numerical simulation of a reactive jet in cross-flow

, 2010
Direct numerical simulation (DNS) with multi-step hydrogen-air chemical kinetics is used to investigate the nearfield of a flame stabilized above a reactive jet in cross-flow (JICF). JICF configurations are typically used where rapid mixing is desirable;

Simulations of edge-flame propagation in turbulent non-premixed jets

, 2007
Ignition, flame propagation and stabilisation have been simulated and analysed in a turbulent jet of non-premixed methane and air. The first order Conditional Moment Closure (CMC) turbulent combustion model was fully coupled with a Reynolds-Averaged ...

Study on the Combustion Behavior of Inhomogeneous Partially Premixed Mixtures in Confined Space

Energies
Reasonably configuring the concentration distribution of the mixture to achieve partially premixed combustion has been proven to be an effective method for improving energy utilization efficiency.

Reconstruction of the Heat Release Response of Partially Premixed Flames

, 2010
The forced response of a swirl-stabilized, partially premixed flame to inlet velocity and equivalence ratio oscillations was experimentally investigated in a model lean-premixed gas turbine combustor.

CHEMISTRY-TURBULENCE COUPLING IN A MODEL OF INHOMOGENOUSLY PREMIXED COMBUSTION

TASK Quarterly, 2003
Results of work on an extension of the turbulent flame speed model used for a mathematical description of partially premixed combustion are presented. The approach is based on the concept of internal coupling between the turbulence of the mixed fuel and

Study on combustion performances of partially premixed flame in a micro-combustor with cavity

Case Studies in Thermal Engineering
Combustion characteristics of a partially premixed flame in a micro-combustor with a wall cavity were studied numerically under various conditions (primary air coefficient, α = 0.35, 0.5, and 0.65).

Simulation of turbulent non-premixed and partially premixed flames using a look-up table

Journal of Thermal Science and Technology, 2014
In this paper, we present a simple combustion simulation technique based on a look-up table approach. In the proposed technique, a flow solver extracts the solutions of the ordinary differential equations (ODEs) of the chemical equations from the look-up
