Studies on counterflow diffusion flames
Certain aspects of counterflow diffusion flames are addressed in the context of one-step Arrhenius-type global chemical reaction. The general Large-activation-energy asymptotic theory for diffusion flames is first revised and then applied to one dimensional counterflow diffusion flames with finite …

Investigation on weakly curved counterflow diffusion flames at infinitely fast chemistry
We investigate the behavior of a counterflow diffusion flame subject to a flow field comprising of a first order potential flow superimposed on a weak second order correction to the potential flow. An Arrhenius one-step irreversible reaction model at infinite Damkohler number and constant density …

Experimental determination of strain rates in stretched laminar diffusion flames
… and radial velocity components of hydrogen-air counterflow diffusion flames (CFDF). An axisymmetric opposed jet burner (OJB) used seeded air in one cylindrical tube, and a hydrogen-nitrogen mixture in the opposing cylindrical tube. Velocity measurements were made at four different operating flow …

Simulations of Nanoparticle Synthesis in Laminar Stagnation Flames
… for studying nanoparticle synthesis in laminar flames is presented. The governing equations are convective-diffusive-reactive partial differential equations that are discretised using the finite volume method. Detailed chemical source terms and transport coefficients are used to close the …

Stochastic modelling of the growth of carbonaceous materials
… chemical mechanism under conditions relevant to flames (temperatures between 1000 and 2500 K, equivalence ratios between 0.5 and 10). The new methodology is used to calculate the rate of different stochastic processes in KMC simulations of PAH growth of premixed ethylene-oxygen flames. The …

Studies in Advanced Oxy-combustion Technologies
… carbon-to-oxygen atom ratio space for laminar diffusion flames.</p> <p>Part I. Oxy-fuel combustion is considered a promising technology for carbon capture, utilization, and storage (CCUS). One of the primary limitations on full-scale implementation of this technology is the significant increase …
