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…
