英文摘要	The subject of this paper is mainly focused on the development and control of the double folium and trifolium lobe pump profiles by using the principle of involute engagement and use the CAD to get the accurately involute profile. Then using the standard k-epsilon turbulence model and PISO algorithm based on CFD software FLUENT. The dynamic mesh and UDF technology is introduced to transient simulation of the interior flow field inside a lobe pump, and the variation of interior flow field under the condition of the lobe rotating is analyzed. It also analyse the influence which produced by the differ in lobes, and then reveal which lobe is the best. The results show that dynamics variation of the interior flow field is easy to be obtained by dynamic mesh technology and the distribution of its pressure and velocity. Because of the small gaps existing between the rotors and pump case, the higher pressure area will flow into the lower area though the small gaps which cause the working area keep with higher pressure all the time. Both of the double folium and trifolium are existing the vortex during the rotting time and its position, size and shape changes all the time. The vortexes even get disappeared in a circle period and there are more vortexes in double folium lobe pump. The velocity and pressure pulsation of trifolium pump are lower than that of the double folium.
