[徵求] 一題流體力學問題

[xe7961 (xe7961)]

說實話這是蔽校的期中考題,

但此題抓不到頭緒該如何下手...

還有請板上神人求解,先謝過各位大大了.

 Consider an incompressible, steady, inviscid flow.The flow is also axisymmetric
and involves swirling motion.

(a) (10 points) Present the steady-state mass and momentum equations for this
inviscid  flow. Use the cylindrical coordinate system..
Hint: be aware of all assumptions that are bing made.

(b) (10 points) How does the circulation Γ in a circular loop of fluid partics

having a radius r evolve?Use the equations from part(a) todemonstrate the result
 you claim.
Hint:think about DΓ/Dt and relate to what you found in (a).

推 mydreamcome:todemonstrate -> to demonstrate
→ mydreamcome:bing -> being
→ mydreamcome: 1.工程數學的向量單元(圓柱座標系統)+質/動量方程式
推 mydreamcome: 2.circulation Γ與時間的關係搭配圓柱座標去解題
→ cmjan0608:設個unit volume在圓柱座標下討論質量守恆跟動量守恆
