Cutting edge spray characterization research conducted at the University of Maryland has deepened the current state of understanding of fire sprinkler spray generation. This research and insight has been extended to the fire sprinkler system design process resulting in a potentially disruptive design tool. The design tool is based on advanced measurements of sprinkler sprays developed over the past ten years of research in this area. This fire sprinkler spray research has demonstrated that laser based Shadowgraphy/PTV measurement techniques paired with a basis function data compression approach effectively characterizes the complex stochastic behavior of sprinkler sprays. This efficient approach provides a compact, computationally-inexpensive, physics-based representation of the sprinkler spray not before possible. This high-fidelity sprinkler spray description is well suited for use in the proposed computer based simulation. A device database for commercially available fire sprinklers will be created using this methodology and included into the software package allowing the user to conveniently assess various types of sprinklers for the modern fire suppression system design challenge of interest without needing to know the details of the complex spray physics.The fire sprinkler industry represents over a $40B market in the United States alone. These fire sprinkler systems are ubiquitous and effective. The absence of analytical tools for evaluating sprinkler system performance can result in unnecessary construction expenses, excessive losses due to water damage, or even worse, needless loss of life and property due to failed fire protection. The current prescriptive design approach utilizes the NFPA fire code for the sprinkler system design. Although straightforward, this pre-computer approach is resource intensive and offers little opportunity to meet the design challenges of modern infrastructure. The proposed approach combines innovative laser-based diagnostics; analytical methods; modern software tools; and novel engineering practices all bundled into a cutting-edge engineering design product. This fire sprinkler performance based design tool offers an innovative computational approach, which addresses the shortcomings of the prescriptive design method. The proposed design tool provides a powerful and convenient design loop facilitating unprecedented system optimization. The visual representation of the sprinkler wetting performance allows users to evaluate the performance of sprinkler systems in protecting standard and unconventional spaces, within the context of NFPA code compliance. This software has the potential to be marketed to a wide range of engineers in the consulting and insurance fields.
