Closure to “Discussion of ‘Factors of Safety for Richardson Extrapolation’ ” (2011, ASME J. Fluids Eng., 133, p. 115501)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Technical Brief by Roache [1] presents ten items of discussion of our factor of safety (FS) method for solution verification [2]. Our responses are listed below item-by-item using the same ...
Factors of Safety for Richardson Extrapolation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A factor of safety method for quantitative estimates of grid-spacing and time-step uncertainties for solution verification is developed. It removes the two deficiencies of the grid convergence ...
Computational Towing Tank Procedures for Single Run Curves of Resistance and Propulsion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A procedure is proposed to perform ship hydrodynamics computations for a wide range of velocities in a single run, herein called the computational towing tank. The method is based on solving ...
Vortical Structures and Instability Analysis for Athena Wetted Transom Flow with Full-Scale Validation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Vortical structures and associated instabilities of appended Athena wetted transom flow in full-scale conditions are studied using DES to explain the source of dominant transom flow frequency, ...
RANS Simulation of Ducted Marine Propulsor Flow Including Subvisual Cavitation and Acoustic Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: High-fidelity Reynolds-averaged Navier Stokes (RANS) simulations are presented for the ducted marine propulsor P5206, including verification and validation (V&V) using available experimental fluid ...
Integral Force/Moment Waterjet Model for CFD Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An integral force/moment waterjet model for computational fluid dynamics (CFD) is derived for ship local flow/powering predictions, including sinkage and trim. The waterjet induced reaction forces ...
