Abstract |
|
|
| This study investigates fire extinguishing efficiency using nanofluid flow through porous sprayers. The nanofluid, which uses magnesium hydroxide (Mg (OH) 2) and zinc oxide (ZnO) nanoparticles along with water as the base fluid has been used. The model equations were solved numerically using MATLAB which employs Runge-Kutta–Fehlberg scheme. Effects of different flow parameters, skin friction and entropy generation were investigated. The study identifies that magnesium hydroxide nanofluid acquire high velocity and temperature than zinc oxide. Furthermore, both nanofluids reduces entropy with an increase in nanoparticle fractions. Also it is observed that there is a slight change in skin friction when using Mg(OH)2 and ZnO nanofluid respectively. These findings underscore the potential of nanofluids in optimizing cooling systems and reducing entropy generation for the better performance in fire extinguishing. |
