| Abstract: | A coupled heat transfer model was constructed for silencer and external atmosphere environment, and the Fluent code was used to calculate the temperature field of a simple expansion chamber silencer. The reasons for internal and external temperature distribution of the silencer and the effect of internal flow on the temperature field were analyzed. Based on the above study, the temperature field of dual-inlet silencer was calculated under a given work condition. |
