“…The authors concluded on this study by stating that surface delamination and exfoliation are crucial to the growth of roll paper fires and also noted that high water rate application and application times were observed to have slight significant effect on the suppression. Furthermore, the impact of water spray on temperature and flame behaviour of vertical wall PMMA slab was experimentally and numerically investigated by Zhao et al 84 The effect of heat flux (6.03-33.2 kW/m 2 ) distribution and flame height (at 50 and 100 s), for varied water application rate (0.0002-0.002 kg/s) are reported. They found that the water spray is capable of strengthening the fire resistance of combustible materials even under high heat flux radiation, which is attributed mainly to external heat flux and combustion property of the material.…”

Water spray remains the most effective, environment-friendly and economical way of fighting accidental or unwanted fires, and this is largely due to its thermal characteristics. The mechanism of fire suppression by sprinkler water sprays is influenced by numerous factors, which have been the focus of years’-long and on-going research studies to improve its extinguishing performances. A comprehensive review study was carried out in this study to assess the level of technological know-how and current state of research in the field. A total of 2473 published articles spanning 50 years (i.e. 1970–2020) were systematically collected and analysed, whereby more than 100 relevant articles were selected and integrated in the discussion. In particular, the review focuses on research relating to the interactions of sprinkler sprays with flame, fire plume and hot surfaces, aiming to provide a better understanding of the phenomena involved in fire suppression.

The collision of drops in a solid substrate is an interesting problem with several practical applications. When the drop is made of a complex fluid the problem presents numerical challenges due to the interaction of the mechanical properties and the free surface approach. In the present work, we solve the numerical problem of elasto-viscoplastic drops colliding in vertical plane. The free surface evolution is handled by a Marker-And-Cell method combined with a Front-Tracking interface representation. Special emphasis is given to the gravitational effects by means of exploring the Froude number. We were able to find a rich variety of outputs that can be classified as sticking, sliding, bouncing, detaching, and slithering.
