Fluid in a rotating cylinder

WebApr 14, 2024 · The cylinder of fluid is stationary and rigidly rotating around its axis of symmetry. It is an anisotropic nondissipative fluid bounded by a cylindrical surface Σ. Its principal stresses P r, P z, and P ϕ satisfy the equation of state P r = P z = 0, which allows one to write its stress–energy tensor—see (1) of Célérier and Santos 3 3. WebIn fluid dynamics, the Taylor number (Ta) ... The typical context of the Taylor number is in characterization of the Couette flow between rotating colinear cylinders or rotating concentric spheres. In the case of a system which is not rotating uniformly, such as the case of cylindrical Couette flow, where the outer cylinder is stationary and ...
