| Abstract: | With the exhaust of one diesel generator units as the background, the structure and performance of muffler were designed by the exhaust parameters and given conditions. The models was built by the hydrokinetics software, gambit and fluent. The fluid fields and the capacities of noise elimination were computed by the numeric simulation. The results showed that the capacities of noise elimination was above 25 dB in the designed muffler. |
