Simplification of micromixing calculations. I. Derivation and application of new model

摘要: Abstract The micromixing model reported by us in 1984 consists of a set partial differential equations to express unsteady diffusion and reaction deforming laminated structures formed engulfment turbulent fluid. This engulfment—deformation—diffusion (EDD) has been widely applied interpret experiments showing an effect mixing on the product distribution reactions between 1-naphthol diazotized sulphanilic acid. Theoretical arguments recent experimental results show how EDD can be simplified neglecting deformation provided that Sc ⪡ 4000 F 1. new E retains fluid as rate-determining step contains no arbitrary parameters. Application two complex shown is also determining, i.e. does not depend diffusion. ordinary equations; it one orders magnitude faster compute wider choice software available for its numerical implementation. Micromixing calculations have accelerated.
