Analytic modeling of turbulent shear flow with chemical reaction

The current state of development of a model for the prediction of the mean rate of reactant consumption, product formation, and heat generation for initially unmixed reactants in turbulent shear flows is reviewed. Of particular interest, here, is the employment of such a model to determine performance of diffusion-type continuous chemical lasers, in which highly dissociated fluorine reacts with bimolecular hydrogen (or deuterium) to form activated fluoride. In recognition that this model applies to the downstream portion of the laser cavity mixing layer, an analytic approach is proposed to develop a (laminar parabolic) model to study the reactive flow in the lasing zone, at the start of this mixing layer.
