Paper Title:
Temperature Field Numerical Simulation on the Exhaust Silencer with Adiabatic Envelope
  Abstract

Exhaust noise is the major noise source of the internal combustion engines, and the exhaust silencer is the device to reduce the exhaust noise. Exhaust gas of the internal combustion engine is high-temperature, therefore in the study of internal combustion engine exhaust silencer, the surface temperature’s influence on the surrounding adjacent facilities should be controlled to a certain range and the status of the temperature field depends on the material and structure of the adiabatic envelope. The model of exhaust silencers discussed in this article is fluid-solid interaction model and this paper uses the CFD software for numerical simulation of the model. Using appropriate boundary conditions, calculation models and silencer model with heat transfer surface, this paper uses N-S equation and standard turbulent model to simulate the flow field and wall temperature field inside the silencer, and does post-processing analysis of the results.
