【Abstract】 A numerical analytic system was established for the study of the internal flow of the axial flow whirlpool combustor in this thesis, based on the real 3-D geometry and powerful commercial software STAR-CD. Two test cases were examined with different second wind inlet area in accordance with the real practice for the control of the flow pattern in the plant. Result indicates that numerical solution agrees quite well with experimental result reported. The system developed in this paper may provide a guideline for the proper control of the combustor.更多还原
