Outline of Final Research Achievements

A new optimization method for compressive flows with sound propagation in complex space is developed. A higher-order accurate IB method and an interface condition based on characteristic lines are derived. In the development of the interface condition, it is extended for non-conforming cases where mesh points do not coincide on the interface.The developed method was incorporated into a fluid analysis software of compressible Navier-Stokes equation based on higher-order accuracy scheme, which is parallelized by MPI. This method was also successfully applied to the problem of introducing longitudinal vortices by wedge rows to a boundary layer formed under hypersonic flows of Mach 6.
