Effect of nozzle design on foam structure and stability and efficiency in fire-fighting applications
article
Firefighting foams need to fulfil specific requirements like delayed drainage, spreading on liquid surfaces and stability over time to function efficiently. The way foam is generated has a significant impact on the foam structure and its structural decay over time. Experiments were designed and performed to establish a correlation between nozzle design, foam structure, stability, and fire suppression performance. With a detailed and statistical evaluation of the results, it was possible to explain the critical role that nozzle geometry plays in influencing foam behavior, particularly in terms of bubble size distribution, stability, and area coverage over time. This information demonstrated that nozzle design significantly affects the formation and stability of bubbles, which directly impacts the foam’s effectiveness in fire suppression applications. These insights fill a significant gap in the existing literature regarding the influence of nozzle design on foam production, and they provide a solid foundation for optimizing nozzle configurations to enhance firefighting efficacy. The research outcomes offer practical guidance for selecting and optimizing nozzle designs tailored to specific fire suppression scenarios.
