The internal flow in a water mist injector for fire suppression applications is investigated, implementing 3D Large Eddy Simulations based on the Volume-of-Fluid methodology. The flow is assumed to be incompressible under isothermal non-reacting conditions. The effect of internal nozzle geometry on the injector behaviour is investigated, for different operating conditions, by modifying the inclined swirling channels. The injector behaviour is mapped varying the injection pressure for each nozzle geometry. Detailed in-nozzle flow analysis is performed.

Abstract
The internal flow in a water mist injector for fire suppression applications is investigated, implementing 3D Large Eddy Simulations based on the Volume-of-Fluid methodology. The flow is assumed to be incompressible under isothermal non-reacting conditions. The effect of internal nozzle geometry on the injector behaviour is investigated, for different operating conditions, by modifying the inclined swirling channels. The injector behaviour is mapped varying the injection pressure for each nozzle geometry. Detailed in-nozzle flow analysis is performed.| File | Dimensione del file | Formato | |
