Abstract

Abstract: Bulging tube failure is common when tubes are exposed to high temperatures. The most prevalent reasons of bulging tube failure are more heating and creep deformation. This research article simulates the most typical causes of tube bulging failure. Coal-fired power station boiler tubes from diverse processing industries display identical bulging tube failures when loaded with pressured fluid and placed inside a higher temperature zone. The differential in temperature between the outside and inner tube walls and compressed fluid inside the tube demonstrates efficient thermal expansion on the metal tube wall in the form of creep ductile deformation. By merging traditional CFD (Computational Fluid Dynamics) and FEA (Finite Element Analysis) models, this research provides a technique based on fluid structures. The thermal-structural behavior of tube deformation can be predicted using a combined CFD-FEA simulation of tube bulging failure. The CFD modeling solves the increment in fluid pressure inside the metal tube and the increment in temperature inside and outside the metal tube. FEA modeling aims to solve the thermal and structural behavior due to radial deformation and thermal expansion caused by thermal loads. Coupled CFD-FEA Simulation swelling tube failure in a hotter zone shown a clear idea of the high pressure and enhanced temperature, creep ductile deformation of tube wall in which the possibilities of tube failure are greater.
