| Abstract: | In order to improve the swirl nozzle atomization under low pressure,the five factors which affecting the low-pressure swirl nozzle atomization were investigated,which were swirling chamber diameter D,swirling chamber height H,nozzle exit diameter d,nozzle exit length l and swirling entrance number n.Sixteen groups of nozzle structural parameters were designed by the way of orthogonal experimental design.The unstructured mesh was gotten with Gambit,the inlet boundary conditions is pressure-inlet and the gaug... |
