| Outline of Final Research Achievements |
The behavior of complex fluids, which contains polymers or bubbles, was investigated by molecular dynamics simulations. We have studied the Kalman vortexes occurring at the rear of the cylinder and found that the vortexes become blurred for fluid with polymers. This phenomenon did not occur when the length of the polymer was short, indicating that the length of the polymer was important. In a flow with bubble formation, the position of the vortex generation shifted to the rear and the reaction from the vortexes on the cylinder disappears. These findings can only be obtained by studying the molecular scale by molecular dynamics methods.
