Resumo

DNS of a turbulent plane jet has been carried out along with the resolution of the RTE in order to analyse the role of the turbulent small-scales on the thermal radiation. LES a-priori and a-posteriori tests have been applied for thermal radiation. The comparison of the results highlights the subgrid-scale influence over the filtered radiation quantities. It is shown that the small scales play a relevant role in the jet edge zone, where the radiative heat transfer is less important. However, at large optical thickness, the role of the SGS-TRI can be significant and may need to be taken into account in the coupling of radiative transfer with LES.
