Abstract

The water spray patterns discharged from an atrium sprinkler are studied in this paper. Equations for calculating the size distribution and the trajectory of the droplets in the water spray are reviewed. The trajectories of water droplets are studied by solving the equation of motion, with the velocity components of droplets expressed in analytical form. A new droplet size distribution function for the water spray derived earlier from information theory was used. The shape of the sprinkler water sprays was calculated. Results are useful in studying the interaction between sprinkler and free-induced airflow. Furthermore, dividing the spray radius into different parts, the volume of water received at the floor level was calculated to determine an important parameter: the water distribution function.
