消防泡沫射流落点强度的关键影响因素分析研究
Analysis and Research on the Key Influencing Factors of the Landing Points Intensity of Fire Foam Jet
摘要
Abstract
Currently,research on factors influencing the landing point intensity of fire foam jets suffers from the lack of physical mechanism support for feature construction and the unclear nonlinear interaction mechanism among multiple parameters.To deeply explore the control issue of the landing point intensity of the foam jet,a new feature with specific physical significance based on fluid mechanics theory is proposed to capture the nonlin-ear interaction effects of multiple parameters during the foam jet process.The random forest algorithm was used to model and analyze the landing point intensity of the foam jet,quantify the importance ranking of each influen-cing factor,and explore the influencing factors and their action mechanisms in the foam jet process during the foam jet process.The results showed that the fluid mechanics characteristics represented by the Froude number(Fr)and Reynolds number(Re)play a decisive role in the influence on the landing point intensity of the fire-fighting foam jet.Specifically,the Fr dominates trajectory stability,while the Re controls energy dissipation rates.These two factors jointly determine the energy foundation of the landing point strength.The explanatory power for model variance is significantly higher than that for other single parameters.This study provides a refer-ence for selecting research priorities regarding the landing point intensity of foam jet in the future and controlling various influencing parameters in fire extinguishing operations.关键词
