A major drawback of Boussinesq-type subgrid-scale stress models used in large-eddy simulations is the inherent assumption alignment between large-scale strain rates and filtered subgrid-stresses. priori analyses using direct numerical simulation (DNS) data has shown that this invalid locally as stresses are poorly correlated with [Bardina et al., AIAA 1980; Meneveau Liu, Ann. Rev. Fluid Mech. 2...

in the procedure of designing an underwater vehicle or robot, its maneuverability and controllability must be simulated and tested, before the product is finalized for manufacturing. since the hydrodynamic forces and moments highly affect the dynamic and maneuverability of the system, they must be estimated with a reasonable accuracy. in this study, hydrodynamic coefficients of an autonomous un...
