Differential diffusion effects and super-adiabatic local temperature in lean hydrogen-air turbulent flames
H. C. Lee, P. Dai, M. Wan +1
Analyzed in this paper are three-dimensional Direct Numerical Simulation (DNS) data obtained from seven statistically planar and one-dimensional, lean complex-chemistry hydrogen-ai…
Towards large eddy simulations of premixed turbulent flames without a combustion model
Andrei N. Lipatnikov
The paper aims at assessing a hypothesis that resolution required to evaluate fuel consumption and heat release rates by directly (i.e., without a subgrid model of unresolved influ…
Intermittency of inter-scale kinetic energy transfer and of energy exchange between internal and kinetic energy in turbulent premixed flames
Vladimir A. Sabelnikov, Andrei N. Lipatnikov
Inter-scale kinetic energy transfer in turbulent flows is accompanied by very intense and intermittent spatial-temporal fluctuations. Such intermittency is expected to be particula…
Transition from turbulence-dominated to instability-dominated combustion regime in lean hydrogen-air flames
Hsu Chew Lee, Peng Dai, Minping Wan +2
Recent complex-chemistry direct numerical simulations of lean hydrogen-air flames propagating in forced turbulence in a box were continued by switching-off the turbulence forcing.…
Turbulent burning velocity and thermo-diffusive instability of premixed flames
HsuChew Lee, BuChen Wu, Peng Dai +2
Reported in the paper are results of unsteady three-dimensional direct numerical simulations of laminar and turbulent, lean hydrogen-air, complex-chemistry flames propagating in fo…
Solenoidal and potential velocity fields in weakly turbulent premixed flames
Vladimir A. Sabelnikov, Andrei N. Lipatnikov, Nikolay Nikitin +2
Direct Numerical Simulation data obtained earlier from two statistically 1D, planar, fully-developed, weakly turbulent, single-step-chemistry, premixed flames characterized by two…
Application of Helmholtz-Hodge decomposition and conditioned structure functions to exploring influence of premixed combustion on turbulence upstream of the flame
Vladimir A. Sabelnikov, Andrei N. Lipatnikov, Nikolay Nikitin +2
In order to explore the influence of combustion-induced thermal expansion on turbulence, a new research method is introduced. The method consists in jointly applying Helmholtz-Hodg…
Early Transient Period in the Evolution of the Area of a Passive Front Propagating in a Strong Turbulence
Vladimir A. Sabelnikov, Andrei N. Lipatnikov
Influence of statistically stationary, homogeneous, and isotropic turbulence on the mean area of a passive self-propagating front and, hence, on the rate of fluid consumption by th…
Thin Reaction Zones in Highly Turbulent Medium
Vladimir Sabelnikov, Rixin Yu, Andrei Lipatnikov
In a highly turbulent medium characterized by a low Damköhler number Da, reactions are commonly considered to occur in distributed zones broadened by small-scale turbulent eddies.…
Turbulent diffusion of chemically reacting flows: theory and numerical simulations
T. Elperin, N. Kleeorin, M. Liberman +3
The theory of turbulent diffusion of chemically reacting gaseous admixtures developed previously (Phys. Rev. E {\bf 90}, 053001, 2014) is generalized for large yet finite Reynolds…
