CFD of ship hull

Today’s computational tools offer a great possibility on the improvement
of the ships hull design. The methods used today are since 2000 the
RANS (Reynolds Averaged Navier Stokes) methods. With the increasing
computational power, not only the hardware, but also the developement of
new very robust and cunning software codes it becomes feasible and
attractive to simulate the performance of the hulls.

Hull design

The design of a hull for a ship can be done in specific CAD environments where the curvatures and dimensions can be controlled. The design can be tested in the CFD software for performance at different hull speeds. It is important to reduce the resistance of the hull.

CFD simulation

The hull once designed can be tested in the CFD software for performance. In the picture above an impression is given of the flow around a customers hull. The resistance at certains boat speed has been investigated.
