book: transport phenomena 2nd edition author:byron bird page111 ex: 3c.3 deformation of a fluid line in couette flow Prolem Detail: A fluid is contained in the annular space between two cylinders of radial Kr and r. The inner cylinder is made to rotate angular velocity of Wi. Consider a line of fluid paricles in the plane z=0 extending from the inner cylinder to the outer cylinder and initially located at O(sita) = 0, normal to the two surface. How does this fluid deform into a curve O(sita) (r,t), what is the length l of the curve after N revolutions of the inner cylinder? 请各位高手们再次帮忙罗!! 有解的话可以麻烦回到我的信箱或是[email protected] 感谢!!~~ 真的有收到您的解的话,一定会好好感谢您的!! -- ☆ [Origin:椰林风情] [From: chap254-198.resnet.stonybro] [Login: **] [Post: 22]
