Numerical Study on the Hydrodynamic Performance of the DARPA Suboff Submarine for Steady Translation
Volume 8: CFD and FSI, 2020Abstract This study was built upon previous works conducted by the authors in a series of numerical studies on submarine hydrodynamics and is aimed at enhancing the accuracy of computational fluid dynamics (CFD) application processes, which estimate the hydrodynamic performance of underwater vehicles for steady translation conditions in ...

Simulation of Flow over Suboff Bare Hull Model
49th AIAA Aerospace Sciences Meeting including the New Horizons Forum and Aerospace Exposition, 2011Reynolds-averaged Navier-Stokes calculations, hybrid turbulence model simulations, and direct numerical simulations were employed for investigations of the DARPA Suboff bare hull geometry which is a prototypical submarine model. The simulations were carried out with an in-house developed Navier-Stokes code. In addition, as a reference, Reynoldsaveraged

Summary of DARPA Suboff Experimental Program Data
1998Abstract : Experimental measurements of the flow fields from an axi-symmetrical body with and without appendages were made in the Carderock Division, Naval Surface Warfare Center (CDNSWC) and Tracor Hydronautics Ship Model Basin (HSMB). These experimental data are intended to serve as the data base for the Computational Fluid Dynamics (CFD) validations

Fundamental CFD Study on the Hydrodynamic Performance of the DARPA SUBOFF Submarine
Volume 2: CFD and FSI, 2019Abstract This study attempts to examine the potential for computational fluid dynamics (CFD) as an estimation tool of the hydrodynamic performance of submarines. The DARPA SUBOFF model is adopted as a benchmark because of its availability of experimental data for validation.

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 ...

Computation of Incompressible Flow Around the DARPA SUBOFF Bodies
1990Abstract : This report describes the application of the DTNS flow solvers, both axisymmetric (DTNSA) and three-dimensional (DTNS3D) versions, and the NUGGET grid generation code to the Defense Advanced Research Projects Agency (DARPA) SUBOFF bodies.

Pressure and Shear Stress Measurement Uncertainty for DARPA SUBOFF experiment
1990Abstract : An uncertainty analysis of the pressure and shear stress measurements in the SUBOFF experiments is presented. Error sources in the measurements are identified, characterized as to the types of error that will results, and then quantified. The propagation of errors in the pressure and friction coefficients is approximated with a Taylor series
