Bunsen flames of unusual structure

Transfer function of acoustically perturbed Bunsen flames. Theoretical investigation

The kinematic models for perturbed flames from [7, 6] are extended to account for flames with arbitrary cone angles and a burning velocity with non constant direction. This extension improves the description of the front close to the boundary and, consequently, the behaviour of the flame response to velocity perturbations. PACS: 43.28.Kt; 47.75.Pq; 02.60.Cb

Conical-shaped travelling fronts applied to the mathematical analysis of the shape of premixed Bunsen flames

Existence of Nonplanar Solutions of a Simple Model of Premixed Bunsen Flames

This work deals with the existence of solutions of a reaction-diffusion equation in the plane IR. The problem, whose unknowns are the real c and the function u, is the following:

Numerical Simulation of Turbulent Bunsen Flames with a Level Set Flamelet Model

An extension to the level set flamelet model of Peters [1] for premixed turbulent combustion that takes the effects of cold ambient air entrainment into account is presented. The model is valid in the flamelet regime, where the reaction zone thickness is smaller than the Kolmogorov length scale. The inner structure of the instantaneous flame front is taken into account by a presumed pdf approac...
