, 1981 本文把用于气流与化学激光性能计算的理论模型作了分析比较,包括常用的Lorentz-Gauss谱线形因子近似、本文提出的矩形谱线形因子近似以及文献[5]的理论。对气流化学激光的简化扩散混合模型,文中简要地导出了与上述诸理论相对应的具体结果。分析和计算表明:在碰撞与非均匀加宽同时起作用,特别是非均匀加宽占优势的情况下,两种谱线形因子近似以及文献[5]理论的结果三者之间存在显著的差异;矩形谱线形因子近似要比常用的Lorentz-Gauss谱线形因子近似精确,而矩形谱线形因子近似的计算量要比Lorentz ...

一様流中にある, 断面比1/0.4角柱のまわりの平均流速ベクトル, および角柱の表面に作用する平均圧力を風洞実験により調べた. / 正の迎角を付けた場合, 上面側の流速が下面側により加速され, その結果上面の圧力の方がより低くなる. 上面と背面との間の後縁付近で流れが逆流し難くなり, それらの間で圧力の不連続が生じることによって正の揚力傾斜となる. / また種々の断面比の角柱の後流において速度分布に相似性が近似的に存在する.1. まえがき / 2. 実験方法 / 3. 揚力傾斜および表面圧力分布 /
