Paper presented at the SNAME Maritime Convention, October 27–29, 2021
Paper Number: SNAME-SMC-2021-053
... This paper addresses the propeller singing mitigation strategy of implementing an anti-singing edge so that the vortex shedding mechanism causing the excitation at the trailing edge of the propeller blade can be reduced. A Reynolds-Averaged Navier Stokes model with a k-ε turbulence formulation...

Paper presented at the SNAME Maritime Convention, September 29–October 2, 2020
Paper Number: SNAME-SMC-2020-010
... Wedge water entry studies are often performed by Naval Architects to estimate hydrodynamic pressure loads on small craft operating in waves. There are a number of theoretical formulations that have been developed in an effort to simplify the process of estimating design loads for vessel design...

... that the free-surface intersects the structure, also known as the spray root or wetted length, and is defined as c. After this intersection point, a thin jet of water propagates away from the wedge. Wagner (1932) first formulated a boundary value problem for a V-shaped wedge entering calm water...

Paper Number: SNAME-SMC-2019-016
... This paper explores the effect of asymmetric conditions, specifically non-zero heel, on the formulation of the ship motion problem using a fully-coupled, linear seakeeping code developed by the author. A theoretical formulation is provided under the auspices of an eliminated symmetry assumption...

... is proposed as a design tool that is computationally less costly than a robust Fluid-Structure Interaction simulation. An analytical flat cylinder formulation was used to calculate the pressure coefficient along the bottom of a rigid V-shaped hull impacting calm water at different time steps. Static...
