Experimental study of water spray dispersion around a surface-mounted cube in atmospheric boundary layer flow

• Development of experimental datasets for validation spray dispersion simulations. Experimental characterisation butterfly and hollow-cone sprinklers sprays. Sprays measured using single-camera, back-lit, high-speed videography technique. Outdoor experiments involving each sprinkler operating near a 2.4 m cube in wind. Measured wind characteristics deposition on surfaces ground. Processes around bluff bodies are central to many engineering applications; notably the design wildfire systems cooling urban areas. Simulation methods such as computational fluid dynamics (CFD) have been widely used prediction analysis wind-body-spray interactions. However, there has lack high-quality data against which simulations can be validated. In this study, detailed outdoor were performed water sprays an isolated mounted ground immersed atmospheric boundary layer. Sixteen conducted, with either or implemented windward leeward side cube. The was ground, high-frequency air velocity measurements taken at three heights characterise layer flow. Separate conducted test enclosure technique measure spatial temporal distributions mass flow rate, droplet size, within spray. Comprehensive is presented that well suited use validating
