The velocity vector and flow field inside the separator with two different inlet internals, four different flow regulating internals and six different coalescing internals are obtained, and the separation features of different internals are analyzed and compared.

Efflux elements in the different hydro - efflux hammer were use to go on experiment by adding pump discharge,and similar water jet reflection and impulse in efflux element were found when pump discharge was large.

Study on the Attached flow and Alteration flow character in fluidic element of down hole pressure intensifier;

Wall attachment frequency of complete fluidic sprinkler′s fluidic element

The distance between wall attachment point and basic circle is a key dimension in the design of complete fluidic sprinkler′s fluidic element.

Application of ion implantation and D-gun spraying technology to improve Operation life for jet element of fluid efflux hammer;

The Matlab language with simulink,the principal tool was applied to simulate and compute interior flow field for jet element,after computing we got each outlet numerical solutions of fluid behavior under light and load condition in order to establish foundation for simulating impact system.

In this paper,flow field inside jet element was simulated with CFD numerical simulation,and the results were analyzed.
