Abstract

The conjugate heat transfer, as part of the general multi-physics approach, was implemented in the commercial CFD code AVL FIRE [1]. The code is based on the finite-volume method adopted for unstructured meshes which can contain computational cells of any shape. The basis of this approach is described in this paper and the test case, the heat transfer and the flow in a matrix of surface-mounted cube, is calculated here by using different modeling approaches. Unsteady Reynolds-Averaged Navier-Stokes (URANS) and Partially-Averaged Navier-Stokes (PANS) are used for numerical simulations.
