【摘要】 针对钝体的角度及阻塞率对回流长度的影响问题,本文用SIMPLEST算法对有限空间内的平面直流射流在等温条件下冲击三角形钝体后形成流场进行了数值模拟。比较了钝体角度以及阻塞率变化对回流区长度的影响,为钝体燃烧器的进一步应用提供流场参数。更多还原

【Abstract】 For the proposes of studying the effect on the L/B scale with the blocking ratio φ and the angle a being changed, author carries out the numerical simulation of the flow field with a direct jet impacting a blunt body under the constant temperature by the SIMPLEST arithmetic, compares the influence on L/B with changing the blocking ratio and angle by the results of calculation under the mathematical model, and further, and further, provides the flow field parameters for blunt body burner.更多还原
