Spray Characteristics Of Fire Sprinklers

Although fire sprinklers have been in use for over 100 years there has been little progress toward developing analytical methods of calculating their effectiveness. This lack of progress is primarily due to absence of information about initial spray characteristics near sprinklers. In this study, experiments were conducted near a variety of sprinkler designs utilizing (1) a pulsed laser sheet and CCD camera and (2) phase Doppler interferometry.
