Abstract

For general power system, the thermal exhaust at the exit of funnel has obvious infrared radiation characteristics. In this paper, funnel exhaust plume about the dynamic system is modeled and analyzed. The 3D flow field of exhaust plumes is calculated based on CFD methods. A calculation method of high temperature exhaust plume's infrared radiation is obtained by spectral band model and calibration with C-G two parameters. And the effect of the detecting azimuth angle on the flow field and the infrared radiation of ship exhaust plumes is analyzed. It can be concluded that with the detection angles’ increasing, the space distribution of the exhaust plume shows a tendency to increase progressively. The difference of the radiation intensity of different detection angles can be up to 32.6%.
