Abstract

Detailed measurements of wave-pattern and nominal wake of a fast displacement ship model A. Olivieri, F. Pistani and R. Penna. , 0072& Continuous increase in computer performances allows significant improvements in computational fluid dynamics (CFD). However, a validation of numerical results, by means of experimental data relative to representative test cases, is still needed. The cooperative project between INSEAN and IIHR (Iowa Institute of Hydraulic Research) has been developed to increase the model-scale database for CFD validation in naval applications [1]. The flow around a model of a fast displacement ship has been investigated both numerically and experimentally with particular attention to the case of Froude number (Fr) equal to 0.28. To evaluate scale effect on the flow field, two different model sizes have been tested by IIHR and INSEAN [2]. In this work the wave-pattern and the nominal wake velocity field
