The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase I project is advance the development of technologies for fire control. In recent years, California and other locations have experienced wildfires in millions of square acres of land, displacing thousands of people and forcing millions to breathe unhealthy air. Better fire control technologies, particularly fire hose nozzles, help address this need. The annual North America market for fire hose nozzles is $250 M. The proposed high efficiency nozzles would enable faster fire suppression, preventing billions in dollars of property damage, reducing risk to first responders, and conserving water. This SBIR Phase I project will advance the development of a fire hose nozzle to enable higher fire suppression rates. Enhancing capabilities of fire hose nozzles without changing operational protocols requires development of non-conventional transition regions in the flow pathway to simultaneously allow increasing flow rate, range and surface area. In this project, the nozzle flow pathway will be optimized to eliminate features causing backflow and non-uniformities. A flow modulation mechanism will be developed for the optimized nozzle to allow changing stream width without sacrificing range or fire-control rates. Fire suppression rates of the optimized nozzles will be measured and compared to the existing state-of-the-art nozzles. An empirical model will be created to estimate both the duration and potential water savings.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个小企业创新研究（SBIR）第一阶段项目的更广泛的影响/商业潜力是推进消防技术的发展。近年来，加州和其他地方经历了数百万平方英亩土地的野火，使数千人流离失所，迫使数百万人呼吸不健康的空气。 更好的消防控制技术，特别是消防水带喷嘴，有助于满足这一需求。 北美每年的消防软管喷嘴市场为2.5亿美元。拟议中的高效喷嘴将能够更快地灭火，防止数十亿美元的财产损失，降低急救人员的风险，并节约用水。 SBIR第一阶段项目将推进消防软管喷嘴的开发，以提高灭火率。在不改变操作协议的情况下增强消防软管喷嘴的能力需要在流动路径中开发非常规过渡区域，以同时允许增加流速、范围和表面积。 在该项目中，喷嘴流动路径将进行优化，以消除导致回流和不均匀的特征。将为优化的喷嘴开发一种流量调节机制，以允许在不牺牲射程或火控速率的情况下改变气流宽度。将测量优化喷嘴的灭火率，并与现有的最先进的喷嘴进行比较。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
