Abstract : Radiating, planar, laminar freemixing is investigated by a boundary layer type analysis with similarity methods. The radiative process is described by either the optically thick, the optically thin or the plane parallel layer approximations. The jet, symmetric wake, asymptotic symmetric wake and the merging of two semiinfinite streams are considered. Although nontrivial solutions are admitted in each of the flows, a nonrestrictive similarity solution is obtained only in the case of the asymmetric wake with constant external flow properties for an optically thick gas. The corresponding analysis for axisymmetric freemixing is not included here, since it previously has been demonstrated that in nonradiative compressible flows only extremely restrictive similarity solutions exist.
