Ansys Fluent: Axisymmetric Injection Of Air Into Water

As discussed in Section 9.3.1, you can solve a 2D axisymmetric problem that includes the prediction of the circumferential or swirl velocity. The assumption of axisymmetry implies that there are no circumferential gradients in the flow, but that there may be non-zero circumferential velocities. WebIn axisymmetric flow problems, both (R, φ, z)-cylindrical and (r, θ, φ)-spherical polar coordinates are commonly used.These are illustrated in Figure 3.3 with the z-axis and polar-axis vertical.The angle φ is the same in both systems. Axisymmetric flows are independent φ, and their velocity component, u φ, in the φ direction is zero.
