A finite element approach to simulate general thermal conduction problems C. Peniguel" & I. Rupp& "EDF/LNH, 6 quai Water BP 49 F-78401 Chatou, France Guyancourt Cedex, France ABSTRACT This paper presents some characteristics of a general conduction module (Syrthes), to be used coupled with CFD codes N3S or ESTET, when handling thermally coupled fluid-solid problems. The paper will focus on numerical techniques used. Details will be given on how periodicity and non isotropic cases are treated. Finally, applications have been included to illustrate the ability of the module to handle, at low cost, heat transfer problems. INTRODUCTION CFD codes have been developped and used for many years at EDF. ESTET (see Gabillard [1]) relies on structured grids and N3S (see Chabard [2]) is using finite elements technique. Initially theses codes were concerned only with the fluid domain, but a need to take into account the heat phenomena in solid and fluid simu
