| Abstract: | A three-dimensional mathematical model was developed to investigate the characteristics of multi-nozzle spray cooling.The simulations were performed using an Eulerian-Lagrangian method. The Sauter Mean Diameter(SMD) of droplets and droplet velocities with two and three nozzles under different nozzle inlet pressures and different mass fluxes were gained respectively.By comparing the spray field of multiple nozzles with that of single nozzle,the impact of the number of nozzles on droplet velocity and the droplet SMD distribution were given. |
