A large-eddy simulation (LES) based on a finite volume method was applied to a liquid turbulent flow with a rapid chemical reaction. The large eddy probability density function model was used as a subgrid-scale (SGS) model for a rapid reaction. The correlation coefficient in the scale similarity model between the variance of SGS concentration and that of test-filtered concentration was determined using the data of the DNS of liquid isotropic turbulence. To investigate the applicability of the LES to reacting liquid flows, both measurement and LES were performed in a liquid mixing layer with a rapid reaction. The prediction of the LES was in good agreement with the measurement. And the result also showed that the present LES can accurately estimate the concentration statistics in reacting liquid flows.
