Moving circle in the closed channel
The following examples concern flow around a moving circle in the closed channel.
The aim of the following simulations is just 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 of the underlying mathematical and numerical concepts is given in Stefan Turek's CFD-book, Springer
The complexity of the physical problem depends on the:
A systematic variation of these different configurations is part of the following flow situations.
