dc.description.abstract | 隨著生活品質的提昇及勞工安全的注重,噪音問題越益受到重視,其中又以流體所誘導的氣動噪音最為複雜。本研究將發展氣動噪音的模擬方法用以分析與改善噪音問題,藉此提升勞工作業環境的品質。本研究的前期將利用流場模擬軟體Fluent建構噴流流場與聲場的模擬方法,首先模擬二維的流場與聲場,之後模擬三種不同速度下穩態流場、聲場、壓力場的狀況。其次模擬三種不同速度下暫態的流場與頻譜分析,最後針對業界常用的Dual-Stream Jet噴嘴減噪方法,對於副噴嘴的管徑與速度做最佳化的分析與探討,模擬其渦流強度分析噪音較大的原因,以期改善勞工作業環境之噪音降低與防治。 | zh_TW |
