Evaluation of Fire Protection Spray Devices:The State-Of-The-Art.

摘要

This report represents a descriptive review of the state-of-the-art on spray nozzle characteristics,drop-size measurement,and drop-size distribution and spray pattern analysis. It appears that the evaluation of fire protection spray devices must be updated to include considerably more than the volume distribution of water at some standardized distance below the deflector of a sprinkler. Since both the fire environment and the spray structure are three dimensional by nature,and,as these opposing forces occur simultaneously in real fire situations,it is desirable to understand in greater detail the application of water to fire by fire protection spray devices.
