Abstract
We researched acoustic analysis on the condition that medium has flow. Simulated by using CIP(Constrained Interpolation Profile) method. We used a flat pulse and a sphere pulse. About flat pulse, we observed the sound pressure. But about sphere wave, it is difficult to search a feature from sound pressure. So we observed the transfer function. We applied uniform flow and Hagen-Poiseuille flow. Hagen-Poiseuille flow is the form in circular tube flow, so we applied circular tube boundary condition. The way is Arbitrary Oblique Reflection Boundary.
