Abstract Large eddy simulation (LES) with the approximate deconvolution model is combined with Lagrangian particles simulation (LPS) for simulating turbulent reactive flows at high Schmidt numbers Sc. The LES is used to simulate velocity and nonreactive scalar while reactive scalars are simulated by the LPS using the mixing volume model for molecular diffusion. The LES–LPS is applied to turbulent scalar mixing layers with a second-order isothermal irreversible reaction at Sc = 600. The mixing volume model is implemented with the IEM, Curl's, and modified Curl's mixing schemes. The mixing volume model provide...

Terashima Experimental study on the reaction rate of a second-order chemical reaction in a planar liquid jet AIChE Journal 60 3969-3988 2014 Accepted manuscript is available  here .  This version is free to view and download for private research and study only.  This article may be found at  https://doi.org/10.1002/aic.14610 . Abstract Instantaneous concentrations of reactive species are simultaneously measured in a planar liquid jet with a second-order chemical reaction urn:x-wiley:00011541:media:aic14610:aic14610-math-0001 to investigate the statistical properties of the chemical reaction rate and the validity of models which have been proposed for concentration correlation. The jet flow contains the reactant A, and the ambient flow contains the reactant B. The results show that the concentration correlation of the reactants makes a negative contribution to the mean reaction rate, and this contribution is important in the downst...
