Abstract
This paper presents a local and global computational study of the flow around the US Navy frigate DTMB 5415 at \(10^\circ \) static drift configuration. A thorough validation study comparing isotropic \(k-\omega \) SST, non linear anisotropic EARSM statistical closures and the unsteady hybrid RANS-LES DES-SST model is conducted. This validation study includes detailed global and local comparisons with IIHR (Iowa Institute of Hydraulic Research) remarkable TPIV experiments. These validations are conducted on a very fine unstructured grid, which includes local boxes of refinement in the cores of the two main vortices, for a total number of 163M cells.
