Prediction of Hull Maneuvering Force Coefficients for a Naval
Combatant Using Computational Fluid Dynamics
	
Predictions of hull maneuvering forces will be performed for
hull form DTMB 5415, which is based on the US Navy DDG51
destroyer.  The predictions shall be performed for combined sway
and yaw motions at a Froude number of 0.280 and compared with
model tests conducted by FORCE Technology and reported by
Simonsen (2004).  The numerical computational fluid dynamics
(CFD) predictions will be performed using the commercial
software Star-CCM+ from CD-adapco.  The CFD predictions will use
a Reynolds-averaged Navier-Stokes (RANS) approach.  The CFD
predictions will consider the bare hull with bilge keels, but
with no other appendages.  Sensitivity studies will examine the
influence of varying grid size and exclusion of bilge keels. 
Deliverables shall be provided in the form of Star-CCM+ input
and output files, and a comprehensive report describing the work
conducted, including development of geometric grids, setting of
computational parameters, comparison of numerical predictions to
model experiments, and sensitivity of predictions to grid size
and exclusion of bilge keels.     

A budget of $69,000.00 Canadian dollars plus applicable taxes
has been set aside for this project.
