New models for conjugate heat transfer

Participant : Rémi Manceau.

New models valid in the near-wall region have been proposed for both the turbulent heat flux and the dissipation rate of the temperature variance in the framework of the EDF CIFRE PhD thesis of G. Mangeon. The purpose is to extend the Elliptic Blending approaches developed in the team to all possible boundary conditions for the temperature: imposed wall-temperature, imposed heat flux or conjugate heat transfer, which is of primary importance for applications in the nuclear industry. The new full model (which associates the two above-mentioned models) is the first one to satisfy all the near-wall budgets and, consequently, the asymptotic behavior of all the quantities. These results have been presented at two international symposia [16], [15].
