To predict the motion of a liquid film and its simultaneous breakup within a liquid jet, we have developed a method that combines the CIP method and the MPS method. We simulated the motion of the liquid film using the CIP method and broke it up using the MPS method. Then the surface tensions between the particles for the MPS method on the free surfaces of the liquid jet were calculated using Brackbill's continuum surface force model. The developed method was applied to a cylindrical liquid jet in a uniform air stream. The helical motion of the liquid film caused it to break up. The configurations of the liquid jet were compared to measurements done by Arai and Hashimoto, and the breakup lengths of the liquid jet agreed well with their measurements.
