Modeling and Simulation of Axisymmetric Swirl Flow | FEATool

Modeling and Simulation of Axisymmetric Swirling Flows

Fluid Flow Simulations with Swirl Effects Fluid flows with swirl effects can occur in rotationally symmetric geometries where the azimuthal or angular velocity component is non-zero. In this case one must solve the fully three-dimensional Navier-Stokes equations. However, due to the assumption that azimuthal variations …
