Abstract

A numerical approach for thermally coupled fluid and solid problems in complex geometries C. Peniguel* & I. Rupp& Chatou, France ^7M(7IOG, ^ ri/e James Jo We Guyancourt Cedex, France ABSTRACT Thermal coupling between fluid and solid domains is widely present in industrial applications. The approach implemented relies upon the existing CFD code N3S (see Chabard [1]), which handles the averaged Navier-Stokes system with a finite element technique, and a module named Syrthes which takes care of the heat equation inside the solid using finite elements technique. An explicit scheme, has proven to be very stable to exchange information (temperature or flux) between solid and fluid domains within each time step. The numerical and geometrical de-coupling of solid and fluid domains has numerous advantages and provides good flexibility when handling complex cases. INTRODUCTION In many industrial applications, a thermal coupling exists between a fluid and the solid body by w
