Lifted flame property and interchangeability of natural gas on partially premixed gas burners
Case Studies in Thermal Engineering, 2018 The relationship between lifted flames and burner head temperature of partially premixed gas burners supplied by various natural gas sources was investigated, and the application of AGA(American Gas Association) lifting limit for Chinese domestic gas ...

Computers & Mathematics with Applications, 2013 This paper is concerned with the analysis of the influence of a partial premixing between fuel and oxidizer at one of the boundaries of a porous walls channel. The mathematical formulation of this problem is performed by means of a constant-density thermodiffusive model under a single-step irreversible chemical reaction.

Flame structure simulation in a methane/air coflow partially premixed burner
Revista Facultad de Ingeniería Universidad de Antioquia, 2014 The effect of the equivalence ratio on the partially premixed methane / air laminar flame structure, in a coflow atmospheric burner was simulated. Three equivalence ratios were studied (Φ=1.6, Φ=2.0, Φ=3.5) keeping constant the released energy.

Measurement and Identification of Flame Describing Function (FDF) Based on Parallel Subsystem Model
AerospaceBecause of the need for low pollutant emissions, industrial gas turbines typically use partially premixed gases for combustion. However, the nonlinear dynamic characteristics of partially premixed flames have not been studied sufficiently.

LES of Partially-Premixed Unsteady Combustion [PDF]
41st Aerospace Sciences Meeting and Exhibit, 2003 Large-Eddy Simulation (LES) methodology has been used to model the combustion dynamics in a realistic swirl-stabilized dump combustor. A novel partially-premixed flamelet combustion model is employed to capture the interaction of the unsteady flame-front with local velocity and equivalence ratio fluctuations. Two sets of simulations have been conducted

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

Polymorph‐Specific Electronic Transduction in WO3 during Molecular Sensing
Advanced Materials, EarlyView.Metal‐oxide polymorphs with similar surface chemistry can nevertheless exhibit distinct sensing properties. In γ‐ and ε‐WO3, analyte adsorption appears comparable; yet, only ε‐WO3 induces a pronounced lattice electronic perturbation that accommodates charge in sub‐conduction band minimum states.
