This Small Business Innovation Research (SBIR) Phase I project investigates the design of a steam modulated water jet that can be used for surface cleaning or material machining operations. The collapse of a steam bubble in subcooled water is known to result in pressure waves of very large magnitude. These pressure waves can be used to fracture and/or remove material from a surface if directed. A water nozzle which periodically injects steam bubbles into subcooled water will be studied. The pressure from the collapsing steam bubbles is directed through an acoustically designed nozzle to the work surface. It is anticipated that the device, when perfected, could be used to remove any affixed material safely and efficiently without degrading the properties of the substrate surface (wood, steel, concrete, or composite) or otherwise fatiguing or damaging the surface. All of the removed material is carried away in a filtered water stream and produces minimum waste and no dust. The successful development of a steam modulated water jet cleaner would result in a new cleaning tool which has no moving parts and the potential for achieving material removal rates heretofore not attainable, with minimum waste, no dust, substantially lower cost, enhanced operator safety, and surface integrity maintained.

这个小型企业创新研究（SBIR）第一阶段项目研究了可用于表面清洁或材料加工操作的蒸汽调制水射流的设计。 已知过冷水中蒸汽泡的破裂会导致非常大幅度的压力波。 如果被引导，这些压力波可以用于从表面破裂和/或移除材料。 本文研究了一种周期性地向过冷水中喷射蒸汽泡的水喷嘴。 蒸汽泡破裂产生的压力通过声学设计的喷嘴直接到达工作表面。 预期该装置在完善时可用于安全且有效地去除任何附着的材料，而不会降低基底表面（木材、钢、混凝土或复合材料）的性质或以其他方式使表面疲劳或损坏。 所有去除的材料都被过滤后的水流带走，产生最小的废物，没有灰尘。 蒸汽调制水射流清洁器的成功开发将导致一种新的清洁工具，其没有移动部件，并且具有实现迄今为止无法实现的材料去除速率的潜力，具有最小的浪费、无灰尘、显著较低的成本、增强的操作者安全性和保持的表面完整性。
