@techreport{oai:jaxa.repo.nii.ac.jp:00043307, author = {安喜, 隆幸 and Aki, Takayuki}, month = {Dec}, note = {Three representative schemes among the TV-stable family were tested for comparing smoothness of solution, resolution power of fluid dynamic discontinuities, and implementation cost. A TVD of Harten-Yee type, its TVB modification by Shu's method, and ENO proposed by Harten-Osher were chosen and use was made with discretization at the second order. Problem tested for space one-dimension was Sod's one and that for two-dimension shock propagation around 90 degree bend in a channel. The tests had been conducted under the same computational conditions Although all the schemes tested showed almost equal resolution for shocks, ENO scheme provided the most smooth solution across shocks. The TVD scheme captured an instability in slip surface associated with Mach reflection. Implementation cost increased in order of TVD, TVB, and ENO. The cost increment of ENO to TVD was less than 10%., 資料番号: NALSP0009016, レポート番号: NAL SP-9}, title = {TV安定スキームの比較}, year = {1988} }
