Abstract:

This report describes the application of the Fluent code to the numerical simulation of the free-surface flow around a model naval ship the DTMB 5415. Simulations were performed using both a structured hexahedral mesh and an unstructured tetrahedral mesh of lower resolution. The results show that Fluent is able to accurately simulate the total ship resistance, near-field wave shapes, and the velocity field in the propeller plane. The results indicate that Fluent is a viable tool which could be considered for use in more demanding naval problems, such as the computation of ship wakes undergoing specified manoeuvres. A number of significant problems were encountered during the course of the work and have been summarized to facilitate future applications of the code to similar naval problems.
