Axisymmetric Flow
Axisymmetric Flow We now turn to inviscid incompressible axisymmetric potential flow Using cylindrical coordinates (r θ z) where = 0 is the axis of the axisymmetric flow and ( ur ) are the velocities in those uθ uz ( r θ z) directions the continuity equation (see equation (Bce11)) is ∂( rur ) ∂( ) + uz r ∂r ∂z |

Theoretical Fluid Mechanics: Axisymmetric Incompressible
1 andAQP 2rotate about the symmetry axis then closed surfaces are formed Assuming that the flow pattern is incompressible the flux of fluid from right to left (in figure 7 1) across the surface generated byAQP 2must match that in the same direction across the surface generated byAQP 1 Let us denote the flux across either of these surfaces by 2πψ |
Are steady axisymmetric flows of an ideal incompressible fluid in multiply connected domains?
In this study, steady axisymmetric flows of an ideal incompressible fluid in multiply connected domains are investigated numerically. The presentation is as follows. In the first section of the paper the equations of motion of an ideal incompressible fluid are considered for the axisymmetric case.
What is axisymmetric flow?
Axisymmetric flow A flow pattern is said to be axisymmetric when it is identical in every plane that passes through a certain straight line. The straight line in question is referred to as the symmetry axis. Let us set up a Cartesian coordinate system in which the symmetry axis corresponds to the z -axis.
Are conformal maps useful in the theory of axisymmetric irrotational incompressible flows?
Conformal maps As we saw in section 6.7 , conformal maps are extremely useful in the theory of two-dimensional, irrotational, incompressible flows. It turns out that such maps also have applications to the theory of axisymmetric, irrotational, incompressible flows. Consider the general coordinate transformation where f is an analytic function.
How axis symmetry can be connected with separatrix surfaces?
In the axisymmetric case the singular points can be connected with separatrix surfaces obtained by rotating two-dimensional separatrices about the axis of symmetry. In the flow domain an external irrotational part of the flow can be separated out ( Fig. 1a ).
