【摘要】 采用分块耦合的网格生成技术 ,利用TTM法生成螺旋流多分支管的三维贴体网格。用任意拉格朗日—欧拉 (ALE)法对螺旋流排气系统中的 2个三分支管模件内的稳态流场进行了数值模拟。揭示了螺旋流排气系统相邻缸排气之间的相互影响 ,为系统地分析螺旋流排气系统的工作机理奠定了基础。更多还原

【Abstract】 Using blocked couple grid generating technology to construct 3D body fitted grids of swirling flow multi branched pipe with TTM methods,the steady state calculations on double swirling flow pipe junctions are carried out in ALE methods.The mutual interferences between the neighboring junctions are found, which laid the foundation to explain systematically the mechanism of swirling flow exhaust system.更多还原
