Numerical investigation of flow structures around the DARPA SUBOFF model
Ocean Engineering, 2021Abstract A large eddy simulation (LES) of a fully appended SUBOFF model was performed by the Boundary Data Immersion Method (BDIM) with the Reynolds number of 1.2 × 107. Numerical simulation is carried out through Fortran-based code and the geometric structure used in this paper is an idealized submarine (DARPA SUBOFF, with appendages).

Free Surface Effect on the Hydrodynamics of an Underwater Vehicle Hullform, the Darpa Suboff
International Journal of Maritime Engineering, 2022This paper presents the numerical study on the hydrodynamic coefficients of the submarine hull form “DARPA SUBOFF” when deeply submerged and near the free surface when travelling straight ahead and at a range of drift angles. The Computational Fluid Dynamics (CFD)-based numerical model was validated with experimental data existing in the public domain ...
