Abstract

Abstract

A monolithic approach to thermal fluid structure interaction with non-conforming interfaces was presented. The thermal viscous flow was governed by the Boussinesq approximation and the incompressible Navier-Stokes equations.The motion of the fluid domain was accounted for by an arbitrary Lagrangian-Eulerian (ALE) strategy. A pseudo-solid formulation was used to manage the deformation of the fluid domain. The structure was described by geometrically nonlinear thermoelastic dynamics. An efficient data transfer strategy based on Gauss points was proposed to guarantee equilibrium of the stresses and heat along the interface. The resulting strongly coupled set of non-linear equations for fluid, structure, heat was solved by a monolithic solution procedure. Numerical example was presented to demonstrate the robustness and efficiency of the methodology.
