doi:10.3901/JME.2017.15.156

Abstract

Abstract: For a four-cylinder engine's turbocharger exhaust turbine, the comprehensive numerical simulation research is performed under high temperature, exhaust-gas aerodynamic load and centrifugal load. In the numerical simulation, computational fluid dynamics and finite element analysis is used to analyze sequential fluid-solid coupling heat transfer. First, the temperature field, the surface pressure field and the boundary heat transfer coefficient distribution are simulated and computed accurately by means of STAR CCM+. These are considered as the third boundary condition and pressure load, which are mapped to the finite element model of the exhaust turbine. The steady-state heat conduction numerical simulation is carried out through ABAQUS to calculate the temperature field and surface temperature of all nodes on the turbine's finite element model grid, and the calculated temperature field is taken as the pre-defined field to implement thermal-stress analysis. Finally aerodynamic load is combined with centrifugal load to perform compound stress analysis.

Key words: exhaust turbine, sequential fluid-solid coupling, thermal stress, turbocharger
