The Kanazawa Theatre), Kanazawa, Ishikawa, Japan, A new flow solver using the compressible LES, Immersed Boundary method and Cartesian grid is developed for automotive internal combustion engine simulation. We incorporated the basic spray model in this solver and carried out parallel spray calculations. This paper presents the results of comparison of the calculation time between two parallel methods. One is particle process method that uses a dedicated process for particle calculation. The other is domain decomposition method in which a process assigned to each domain calculates spray and gas and communicates with other processes to send and receive particles which go outside and inside the domain. Under the condition in this study, we find that domain decomposition method is faster than particle process method., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1630031023, レポート番号: JAXA-SP-16-007}, pages = {173--176}, publisher = {宇宙航空研究開発機構(JAXA), Japan Aerospace Exploration Agency (JAXA)}, title = {境界埋め込み法を用いた等間隔直交格子ソルバにおけるDDM並列計算}, volume = {JAXA-SP-16-007}, year = {2016} }
