Numerical Research on Heat Transfer of Silencer Layer in Narrow Space

Abstract

Jet flow that the engine generates can cause serious damage to facilities and equipment in narrow space. In order to solve this problem, the lowest silencer unit in the silencer layer was selected as research object. The highest temperature of jet flow near silencer unit and thermo-physical parameters at that moment were taken as initial conditions to research on heat transfer. By using the MATLAB software, the heat transfer between jets flow and silencer layer was calculated, the temperature distribution inside silencer layer at different time was obtained, and the law of heat transfer was concluded, which could provide some theoretical basis for the design and upgrading of narrow space.
