Abstract: A second-order accurate coupling algorithm for Thermal Fluid-Structure Interaction (TFSI) is presented. An implicit partitioned solution approach, which combines the advantages of weakly and strongly coupled schemes, is used. The framework consists of a finite-volume solver in arbitrary-Lagrangian-Eulerian formulation for the flow simulation, a finite-element code for the structural part and a commercial, black-box coupling interface. The thermal coupling is realised by a Schwarz decomposition method. Several elementary configurations are considered, to test the accuracy and to investigate the numerical characteristics of the system. By applying different grid configurations, we show that the results are of second-order accuracy. We also discuss the convergence properties of the method.
