Application of the immersed boundary method for the simulation of incompressible flows in complex and moving geometries

Abstract

A new variant of the Immersed Boundary Method (IBM) has been implemented into an established flow solver. Important aspects of the implementation towards the application of this approach for flow simulations in complex and moving geometries are characterised. Simple validation test cases are addressed first, followed by a moving boundary example and more complex geometries like the Weibel lung model. © 2010 Springer-Verlag Berlin Heidelberg.
