用蜂窝陶作为新型热动力的排气消声结构，其不仅具有阻性与抗性的综合功能，且结构工艺简单，因此有很好的应用前景。本文研究蜂窝陶的流动阻力损失和降噪性能。实验结果表明，在同一（相近）工况下，随着蜂窝陶目数增加，降噪效果提高；长度加长，其降噪效果也提高，但当长度大于某一数值后，降噪效果趋缓，而其阻力损失继续增大。综合考蜂窝陶的降噪能力及其流阻损失，在工程应用中应选择合适的结构尺寸。本文为此提供实验与理论依据 Honeycomb pottery as a new thermal power of the exhaust muffler structure, which not only has the combined function of resistance and resistance, and the structure of the process is simple, so there is a good prospect. In this paper, the flow resistance loss and noise reduction performance of honeycomb ceramics are studied. The experimental results show that under the same (similar) conditions, the noise reduction effect increases with the increase of honeycomb pottery number. When the length is longer, the noise reduction effect also improves. However, when the length is greater than a certain value, the noise reduction effect is slowed down , While its resistance loss continues to increase. Integrated test honeycomb ceramic noise reduction capacity and loss of flow resistance, the engineering application should choose the appropriate size of the structure. This article provides experimental and theoretical basis for this
