内燃机电站废气消声多通道结构算法描述

Algorithm of Multi-hole Structure for Reducing Exhaust Noise on Internal Combustion Engine Power Plant

通过对内燃机的排气噪声源的分析,在突变截面管的基础上就单节多通道结构采用波动方程理论,对其消声量的算法进行了探讨,为优化设计、简化计算过程提出了参考方案。

Through the analysis of the acoustical source of the exhaust noise created by intemal combustion engine, the waveequation theory is used in single section multi-hole structure on the base of variable-section tube. The algorithm for reducing noise is explored. Meanwhile, the reference method is given in order to improve design and simply the process of calculation.
