Answer to Question #296976 in Mechanical Engineering for bhargav

Question

 The velocity components in a two dimensional flow are :

U = 8x^2 y - 8/3 y^3 And

V = -8xy^3 + 8/3 x^3.

Show that these velocity components represents a possible case of an irrotational flow.

Answer 1

Irrotational flow is a flow in which each element of the moving fluid undergoes no net rotation with respect to a chosen coordinate axes from one instant to other. A well-known example of irrotational motion is that of the carriages of the Ferris wheel
