Advection-modulated gaseous diffusion through an orifice
Mario Sánchez Sanz, Antonio L. Sánchez
We examine flow and transport through an orifice in a flat wall separating semi-infinite atmospheres of two dissimilar gases. The analysis assumes steady conditions and order-unity…
Influences of stoichiometry on steadily propagating triple flames in counterflows
Prabakaran Rajamanickam, Wilfried Coenen, Antonio L. Sánchez +1
Most studies of triple flames in counterflowing streams of fuel and oxidizer have been focused on the symmetric problem in which the stoichiometric mixture fraction is . There…
Near-limit H-O-N combustion in nonpremixed counterflow mixing layers
Jaime Carpio, Prabakaran Rajamanickam, Antonio L. Sánchez +1
Numerical computations employing detailed chemistry are used to characterize the different combustion modes emerging in mixing layers separating nitrogen-diluted counterflowing pla…
Non-Boussinesq stability analysis of natural-convection gaseous flow on inclined hot plates
Prabakaran Rajamanickam, Wilfried Coenen, Antonio L. Sánchez
The buoyancy-driven boundary-layer flow that develops over a semi-infinite inclined hot plate is known to become unstable at a finite distance from the leading edge, characterized…
A model for the constant-density boundary layer surrounding fire whirls
Adam D. Weiss, Prabakaran Rajamanickam, Wilfried Coenen +2
This paper investigates the steady axisymmetric structure of the cold boundary-layer flow surrounding fire whirls developing over localized fuel sources lying on a horizontal surfa…
