| contents | In this article, we present the governing equations for the temperature field upstream and downstream of the periodically developed flow region in channels with arrays of periodic solid structures. From the ansatz that the temperature field in this region is determined by exponentially decaying modes, just like the quasi-developed flow field, we arrive at an eigenvalue problem which governs the allowed temperature modes. This eigenvalue problem is virtually identical to the one for periodically developed heat transfer in isothermal solids, except that the conjugate heat transfer in the solid is effectively taken into account. |
