Étude des transferts couplés par convection et rayonnement dans un écoulement de type couche limite de fluide thermodépendant non gris: application d'un modèle statistique à bandes étroites

The radiative contribution, as well as the thermodependence effect, are brought to the fore during the coupled exchanges by radiation and forced convection in water steam, supposed to be a semitransparent non-gray medium. Modeling by finite volumes and zone description of the radiative approach adopted in this analysis led to the characterization of cinematic, thermodynamic, thermoradiative and exchange variables for the non-established forced internal flows with great transverse input. Results obtained in bidirectional configuration allow us to interpret some diversions of simple studies related to the gray fluid with regard to the real phenomenon during the exchanges. This work can be completed with a spectral refinement, more dense in tridimentional complex geometries.
