In batch transportation of finished oil products, mixed oil would be produced by adjacent batch oil. The cases of 30°, 45°,60° or 90° for the joint line of the variable diameter part and the straight pipe of the variable diameter pipe were calculated by the CFD software. The conclusion show the relationship and the change law between the angle of the joint of the variable diameter part and the length were researched. The results show that with the angle increased, the mixed oil segment length decreased in the sudden expansion pipe and the opposite conclusion in the reducer, which was coincided with engineering basic phenomenon.
