【Abstract】 In this paper,a review of some traditional emulsifiers has been summarized.On the base of emulsifying theory and reports from authors all over the world,a new type and high efficiency emulsifier was designed.In order to obtain more information about this equipment,the turbulent flow characteristics was modeled using Navier-Stokes equations and standard-model,which was solved by commercial software FLUENT6.0.The results showed that the velocity,pressure and energy dissipation of jetting zone are symmetric with the axis,therefore,the jetting zone is an efficient flow field for heat and mass transfer,which is important for emulsification.更多还原
