Previous simulations of the propeller-ship configuration have shown that a true time-dependent rotor-stator interface provides a significantly higher level of accuracy than steady-state simulations using a sliding mixing plane. The unsteady approach also provides pressure fluctation data on the hull and rudder which are a main source for noise and vibration within the ship.

The new work allows ship hulls to be optimized based on not only their drag, but also on the interaction of the propeller and hull. This will allow for designs which can achieve a desired speed at a lower power requirement.

"The collaboration between SVA and CFX has resulted in many significant improvements of the CFX software, which makes CFX the preferred choice in marine applications. We are committed to ensuring our software meets the demands of our maritime customers," endorses Florian Menter, Head of Development at CFX-Germany.
