Abstract:
Based on a new me thod to produce flu id ice, w ater atom ization in imm iscible o il flow is sim ulated num er-i cally in th is paper. A se t o f three-dim ensional trans ient conservation equa tions o fm ass and m om entum a re estab lished by tak ing surface tens ion and g rav itational fo rce e ffects into consideration. The governing equations are so lved by using Pressure Im plic it Splitting Operators ( PISO) a lgor ithm. The vo lum e-o-f flu id ( VOF) m ethod in con junction w ith them ult-i d im ensiona l p iecew ise linear inte rface construction ( PLIC) is app lied to characterize the behav ior of w ateroil interfacem ovem en t. The flow phenomena in d ifferent w ork ing cond itions are researched. The results o f sim ulation show that the average atom iza tion diam eter ofw ate r droplets increases w ith the v eloc ity of wa ter and decreasesw ith the veloc ity o f o i,l and it increases w ith the diam e ter o f atom iza tion p ipe.
