A Large-Eddy Simulation (LES) based on a finite volume method was appliedto turbulent liquid flows with moderately fast and rapid chemical reactions. The large-eddy probability density function (LEPDF) model and joint LEPDF model were used as a SGS model for a rapid reaction and for a moderately fast reaction, respectively. To investigate the applicability of the LES based on the proposed SGS models to neutrally, stably and unstably stratified reacting liquid flows, the results of the LES were compared with the measurements. The predictions of the LES were in good agreement with the measurements. The results also show that the present LES can accurately estimate the concentration statistics in neutrally, stably and unstably stratified liquid flows with reactions.
