Experimental investigation of the flow around a fast displacement ship hull model

The aim of the present paper is the description of the flow around a fast displacement ship hull model with particular attention on the mechanisms responsible for the generation of streamwise vortical structures along the hull boundary layer. The collected data contribute to a surface-ship resistance and propulsion model-scale database for computational fluid dynamics validation as part of an international cooperative project between Istituto Nazionale per Studi ed Esperienze di Architettura Navale (INSEAN), Iowa Institute of Hydraulic Research (IIHR), and David Taylor Model Basin (DTMB) on experimental and computational fluid dynamics and uncertainty assessment for a combatant geometry (Stern et al 2000). A cross validation of the present results has been carried out through the ones obtained at DTMB and IIHR. Uncertainty assessment of the results has been evaluated following the AIAA Standard S-071-1995.
