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. In this section, we will … WebBut what is the difference between axisymmetric and axisymmetric swirl. Swirl is for when there is out of plane velocity, like here . I suppose axisymmetric ignores angular momentum terms and assumes flow has strictly axial/radial components. Axi-with swirl includes angular momentum terms.
