This report and associated online training detail the results and analysis from the air entrainment testing. These tests were conducted without the presence of fire, to gain a fundamental understanding of how hose streams entrain air. Each set of experiments was intended to add to the understanding of air entrainment and pressure from fire service hose streams by evaluating the differences caused by various application methods, hose stream types, nozzle movements, pressures/flow rates, manufacturers, and ventilation configurations.

“Understanding the concept of air entrainment can aid firefighters in being more effective. Applying these concepts to structural firefighting allows for better control of air during both interior and exterior operations.”

-Stephen Kerber, Director UL Firefighter Safety Research Institute

Part I of this project looked at Water Mapping and Part III of this project looked at Full Scale Fire testing.
