摘要：A stresses are generated due to temperature fluctuations in regions where cold and hot flows areintensively mixed together. Such situation of mixing appears in turbulent flow through a junction in pipe Tee.Fluctuating stresses imposed on a system are potential causes of thermal fatigue failures in energy cooling systems of aplant. The turbulent mixing in a junction is investigated by a coupled approach of fluid-flow calculations andmechanical calculations. Whenever there is a significant exchange of energy between a moving fluid and a solidstructure the widely use of Fluid-Structure Interaction (FSI) analysis is done. Therefore, in this study thermal fatigueevaluation of flowing system at mixing junction is performed using the Fluid-Structure Interaction (FSI) analysis.Using thermal hydraulic analysis, temperature distributions at different zone are determined and their results areapplied to the structural model of the piping system to determine the thermal stress.
