Abstract: Spiral pipe has been widely used in oil-water separation field with the simple structure and other advantages. As an alternative method the numerical research methods have been applied in spiral pipe research. Using the model of VOF, a numerical simulation was done on oil-water two phase flow for spiral pipe and got its spiral flow characteristics. It supplyes the technology of spiral pipe provides with certain basis theoretica:oil-water separation degree is up to 95% in the ninth laps and it is larger near the entry, water phase distribution is little along with the direction of gravity and oil-water heavy mixing phenomenon emergences. Near the entrance turbulent kinetic energy intensity and dynamic pressure changes fluctuating, dynamic pressure decreases linear along the axial except for the entrance. Shear stress is the largest in the entry and change less on axial. It can provide a theoretical support to the development and the improvement of spiral pipe technology.
