@techreport{oai:jaxa.repo.nii.ac.jp:00043341, author = {滝, 史郎 and Taki, Shiro}, month = {Nov}, note = {A solution-adaptive multilevel grid method is developed and applied to solve unsteady high-speed burning gas flows using explicit finite difference method. Heating by interaction of oblique shock waves will support high-speed combustion for some conditions. In the present study, stoichiometric methane-air mixtures are considered as combustible gases, where the four-step reaction model is adopted. The diffusion of species and the heat conduction are considered, but the viscosity is neglected. The results show that in the present conditions flames are blow off, but a detonations can be formed if strong blast waves are used as an igniter. In two-dimensional generalized curvilinear space, the newly developed solution-adaptive multilevel grid method worked well for unsteady burning to reduce the lattice points to be calculated., 資料番号: NALSP0010012, レポート番号: NAL SP-10}, title = {衝撃波で支持された超高速燃焼の数値シミュレーション}, year = {1989} }
