- Abstract
- In order to characterize the water spray from a low pressure, high momentum water mist nozzle, measurements were made using an optical array probe droplet analyzer. The water droplet sizes and velocities from the nozzle were measured at varying operating conditions and locations in the spray field. The study resulted in droplet size and velocity ranges for the nozzle, as well as mean droplet velocities and droplet size distributions. The pendent nozzle used in this study is currently being evaluated by listing organizations for fire suppression in residential and light hazard occupancies.
