Fluid in a rotating cylinder
WebReal Cylinder Flows Real viscous flow about a circular cylinder at large Reynolds numbers exhibits large amounts of flow separation and drag. Normally the flow is symmetric between top and bottom, and hence the lift is zero. WebH p a r a b o l o i d = 2 ∗ H c y l i n d e r. where H c y l i n d e r is the height of air when it is not rotating, 0.2 m, therefore. H p a r a b o l o i d = 0.4 m = y. substituting the value in the equation, y = ω 2 x 2 2 g. where x = 0.1 …

Web11.6 Consider the steady laminar flow of a fluid between two concentric cylinders, with the inner cylinder rotating at an angular velocity ω, as shown in Fig. 11.7. There is no flow in the axial direction, and the tangential velocity depends only on r; that is, v z = 0 and v 0 = v θ (r). Develop the appropriate form of the N-S equations for ...
