1.论述湍流边界层、圆管湍流、明槽湍流这三种基本湍流的壁面剪切湍流的异同；
2.理想化的边界层转捩过程可分为几个阶段？湍流有哪些主要特征；
3.简述湍流猝发现象和过程，并介绍一种检测湍流猝发周期（或频率）的方法。
天煞的，天晓得该去哪里借书…又要泡图书馆了…

恩。。。北航的才子哇，果然不一般我大学4年就没去过图书馆。。。。
呃。。。不是。。。我放在这里是诚邀各界好汉，有知道答案的告诉我一下。。。
明槽湍流是第一次见不太记得了但雷诺系数应该有所反应的
鸦鸦也是工科的？
Actually I am not sure how I got your space either.Probably by coincident…I am a student of Beihang.Anyway, nice to meet you.
快点给我更新
呃……湍流……航空上空的两朵乌云？
想起来了，第二题好像是两个或者三个阶段吧。湍流的特征在刘沛清的课件里有。
回 呢喃：嘿嘿，马上马上～回 gemini：第二题是最容易的，关键是第一和第三，猝发那个我现在还没找到书呢～
The thing is that I am not a junior.Simon is ur teacher? Oh, I see. He is so nice, right?Sorry I don’t know Zhang Pingping.:-)
