These problems can be cured by A) preconditioning on the time-derivative term, and B) control of numerical dissipation, respectively. There have been many proposed methods thus far for A) and B) separately, but it is unclear which combination is "best" in low speed flows. We carried out a comparative study of well-known or recently-developed A) preconditioned implicit schemes coupled with B) low-dissipation Euler fluxes in the framework of steady flows. Then, accurate, efficient, and robust methods are suggested for low speed computations., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0064672017, レポート番号: JAXA-SP-09-011}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {低速流れにおける前処理付き陰解法と低散逸流束関数の性能比較}, volume = {JAXA-SP-09-011}, year = {2010} }
