用于声学清洁的方法和系统
摘要：
本发明名称为“用于声学清洁的方法和系统”。音调发生器组装件(100)包括共振箱(102)，共振箱包括第一端和第二端以及在它们之间延伸的机身(122)，机身在其中包围空腔(124)，第一端包括与该空腔流体连通的共振箱开口；以及喷嘴(104)，喷嘴包括穿过其中的孔(119)，孔包括配置为接收相对高压流体(116)的流的进口(114)以及与进口以流体连通的方式耦合的出口(118)，出口配置为当在进口接收相对高压流体的流时释放流体的不完全膨胀的射流(142)，其中将共振箱(102)和喷嘴相对地放置并且调整其大小，以便利于从音调发生器组装件中发射音调，该音调具有低于两千赫兹的频率并且被调谐到确定用来提供清洁振动能量的频率。
摘要（英）：

A tone generator assembly (100) includes a resonance chamber including a first end and a second end and a body (122) extending therebetween, the body surrounding a cavity (124) therein, the first end comprising a resonance chamber opening in flow communication with the cavity, and a nozzle comprising a bore (119) therethrough, the bore comprising an inlet opening (114) configured to receive a flow of relatively high pressure fluid (116) and an outlet opening (118) coupled in flow communication with the inlet opening configured to discharge an underexpanded jet (142) of fluid when the flow of relatively high pressure fluid is received at the inlet opening, wherein the resonance chamber and the nozzle are positioned relatively and sized to facilitate emitting a tone from the tone generator assembly having a frequency less than two kilohertz and tuned to a frequency determined to provide a cleaning vibratory energy.
