| Abstract(in English) | The constrained interpolation profile (CIP) method is a calculation method with less numerical dispersion error, which uses the values of acoustic field and their spatial derivatives at grid points to solve the problem ofwave propagation. In the study, we investigate the type-C CIP and type-M CIP methods as a method considering the background flow in the acoustic field. The difference between the type-M and type-C CIP methods is thehandling of a second-order special derivative. The type-M CIP method uses the linear interpolation to calculate the advection of the perpendicular derivatives. The type-M CIP method is a simple technique with smaller memory use and less calculation time required than the type-C CIP method. Then, the calculation results are evaluated and compared with those by the exact solution and the linearized Euler equation method. |
