Abstract

Support for large-scale computing is requested. We are working on simulation of the phenomena of turbulent thermal diffusion and tangling clustering instability in temperature stratified turbulence, which have been predicted theoretically but were not obtained in numerical modeling yet. Part of this computations is continuation and further development of the previous work of N. Haugen, N.Kleeorin, I. Rogachevskii, A. Brandenburg, Phys. Fluids 24, 075106 (2012). Another part of the proposal is simulations of combustion regimes of with a detailed chemical kinetics and with special attention given to turbulent combustion and the transition from deflagration to detonation. The calculations are carried out using the code based on splitting of the Eulerian and Lagrangian stages, known as coarse particle method. The code uses MPI and contrary to many other codes allows including detailed chemical kinetic schemes for large amount of species and reactions.
