简介:为一艘通用护卫舰的exhaust烟分散通过管理液体流动,精力,种类和骚乱方程的数字答案数字地被调查。这个工作的主要目的是在exhaust烟的分散上获得yaw角度,速度比率和快活的效果。数字方法基于充分椭圆形的海军司烧方程的充分保存的控制卷表示。骚乱被建模用一二方程(k-?)模型。用在风隧道的护卫舰的一个1/100规模模型的流动可视化测试也被执行决定exhaust羽毛路径并且验证计算结果。结果显示出那在下面洗现象为在蠄=10掳和20掳之间的yaw角度发生。结果与不同用尽快活效果与增加exhaust气体温度增加的煤气的温度表演。然而,它在羽毛上升的效果与它的动量比较是不太重要的。在预言和实验结果之间的一个好协议被获得。
