Abstract

This paper describes on introduction of CASE 3 for EFD-CFD comparison workshop which is incharged of aerodynamic subcommittee of The Korean Societry or Aeronautical and Space Science. In addition, the results of candidate for CASE 3 were compared with experimental result and computational result. Currently, for this case 3, there are eight candidates from company, university and research institute. According to comparison of their results, they are in accordance with experimental data and computational data.

본 논문에서는 현재 한국항공우주학회 공기역학부문위원회에서 주관하고 있는 EFD-CFD 비교워크샵의 여러 과제 중 CASE 3 천음속영역 유동해석에 대해 소개하고 현재까지 참여한 기관들의 결과를 서로 비교하였다. 현재까지 이 과제에 대하여 산학연 8개 기관이 참가하였고, 그 결과 풍동실험결과와 비교적 잘 일치하며, 서로의 해석결과 역시 잘 일치함을 알 수 있었다.
