Rotating propeller flow

The following examples concern flow in a chamber with a rotating propeller inside.

The aim of the following simulations is to demonstrate the utility of our "Fictitious Boundary Conditions": All calculations are performed on ONE SINGLE mesh which does not change! The position of the actual boundary is determined via "filters" and incorporated into the iterative solvers! A more detailed description is given in Stefan Turek's CFD-book, Springer.

The complexity of the physical problem depends on the:

• size and shape of the rotor and the chamber
• rotational speed
• external inflow and outflow conditions

A systematic variation of these different configurations is part of the following flow situations.

• Rotating propeller in a box for a low Reynolds number
• Rotating propeller (I) in a box for a medium Reynolds number
• Rotating propeller (II) in a box for a medium Reynolds number
