Numerical case studies of vertical wall fire protection using water spray
To explore fire resistance capability of vertical wall protected by water spray, a validation scenario is designed and computation is performed. The PMMA slab, which is used to simulate the combustible material, is fixed on a 20 mm thick insulation plate and is exposed to external heat flux. The dimension of the slab is 5 mm×200 mm×1500 In addition, the effect of spray properties such as Q ″ ¯, H and T in on the heat transfer performance of vertical surface spray cooling have been revealed. A quantitative evaluation of these effects and a general correlation of Nusselt number ( Nu ) for single-phase regime has been proposed with deionized water as coolant.Performance of spray cooling with vertical surface orientation: An

Spray Cooling of Vertical Inline Horizontal Tubes ScienceDirect
The effect of water pressure and air pressure on the rapid cooling of vertical inline horizontal tubes has been investigated. As air pressure rises, the quenching temperature of each tube decreases. A high-speed video camera was employed to investigate the flow behavior on the top tube surface as well as the spread of the re Spray cooling is a technique in which a liquid is fully pressurized before being atomized into droplets through a nozzle, then rapidly ejected to a hot surface, which removes heat with droplet impact, film motion, bubble formation, and environmental convection [1].
