On the effectiveness of air-shrouding nozzles on reducing exhaust air noise levels associated with the use of blow-off air guns
碩士 === 大仁科技大學 === 環境管理研究所 === 101 === This study way conducted to investigate the effectiveness of air-dhrouding nozzles on reducing noise levels at audible frequencies. Shrouding air will decrease the velocity gradient formed between the high-speed jet and the ambient air. Thus, this approach is ef...
