| Abstract: |
| A high order parallel algorithm was developed for the simulation of supersonic complex multi-scale flows.The fifth-order upwind compact scheme based on finite volume method was utilized,and the characteristic limiter was used to prevent non-physical oscillations across discontinuity.The fifth WENO schemes were used in adjoining boundaries to achieve consistent precision order in the whole computing domain.Using zone decomposition method and message communicating interfaces,parallel calculation is carried out on MPI platform.The capability of the algorithm is demonstrated by solving supersonic test cases,and the parallel efficiency and speedup are analyzed.Then the algorithm is used for the simulation of supersonic transition and turbulence.The computed results reveal that the developed algorithm has the properties of high-order accuracy and high resolution.Besides,the computed flow fields are conti-nuous in adjoining boundary,and the parallel computing efficiency is acceptable.The algorithm achieves admirable effect in the numerical simulation of supersonic turbulence. |
