Abstract
Temperature-dependent reaction in homogeneous turbulence laden with fuel droplets is investigated via numerical simulation. Homogeneous shear and isotropic decaying flows are considered here as main configurations; however, some discussions also are presented with reference to stationary isotropic turbulence. Comparisons also are provided between constant- and variable-rate reactions. For all the simulations a two-way coupled Eulerian?Lagrangian formulation is implemented in the context of compressible flows. The results are utilized to investigate the evolution of the temperature, the fuel vapor mass fraction, and the reaction zone. Extensive data also are provided for correlations between the reaction rate and various flow parameters. These data are used to reveal some of the minute features of two-phase turbulent reactive flows, which clearly exhibit the importance of various timescales involved.
