Abstract

Purpose. The objective of the research is to analyze the influence of nozzle diameter, grid presence, grid cells area and number of aeration holes on the parameters of sprayed water jet formed by water-foam nozzle and to define performance characteristics of the water-foam nozzle.

Methods. Prototypes of water-foam nozzle were tested on water flow, jet range, effective jet range, spray angle and average sprinkling intensity.

Findings. Influence of nozzle diameter on water flow and spray jet parameters is determined. The necessity of installation of grid with 1 mm2 cells into tested water-foam nozzle is proved. The appropriate number of aeration holes for tested nozzle is defined. Application field of the research. The obtained experimental study data could be used in fire nozzle design.

Conclusions. The prototype with 11 mm nozzle diameter, 1 mm2 grid cells and 5-7 aeration holes is the most optimal version for discharging water. It has better performance characteristics than a regular nozzle.
