| Popis: | International audience; The main objective of this paper is to present a methodology to carry out transient Conjugate Heat Transfer (CHT). Transient thermal interactions between a fluid and a solid are difficult to perform because of their computational cost. Indeed, fluid and solid characteristic times differ by several orders of magnitude. The present method has the aim to speed up the thermal analysis process by coupling an unsteady conduction computation with a sequence of steady CFD computations. This procedure assumes that the influence of fluid unsteadiness is negligible. Moreover, this paper proposes different approaches to interpolate fluid information between two steady CFD computations necessary to the solid solver for moving forward in time. The results obtained with these different approaches are compared with a reference result. |
