Spray flamelet structures in a tubular counterflow configuration
Francisco Rivadeneira, Felipe Huenchuguala, Arne Scholtissek +3
In this work, spray flamelet structures subject to curvature are systematically studied, emphasizing the ways in which this quantity modifies the budgets of the corresponding flame…
Solutions of the spray flamelet equations in a non-monotonic mixture fraction space
Felipe Huenchuguala, Luis Fuenzalida, Oscar Orellana +4
Solving the spray flamelet equations in composition space is very challenging, which is attributable to the fact that the maximum value of the mixture fraction, , i…
Unsteady solutions of the spray flamelet equations
Felipe Huenchuguala, Francisco Rivadeneira, Arne Scholtissek +3
Solutions of the spray flamelet equations reported in the literature during the last decade have been limited to very specific situations presenting steady evaporation profiles onl…
Advantages of the adoption of a generalized flame displacement velocity as a central element of flamelet theory
Hernan Olguin, Pascale Domingo, Luc Vervisch +2
In combustion theory, flames are usually described in terms of the dynamics of iso-surfaces of a specific scalar. The flame displacement speed is then introduced as a local variabl…
On the closure of curvature in 2D flamelet theory
Hernan Olguin, Pascale Domingo, Luc Vervisch +2
So far, flamelet theory has treated curvature as an independent parameter requiring specific means for closure. In this work, it is shown how the adoption of a two-dimensional orth…
