“…Prediction of resistance is the oldest application of CFD in ship hydrodynamics and its accuracy has improved significantly. Simulations show an average error of 3.3%  (displacement) for resistance in both high and low Fr (Froude number) scenarios in recent studies [3]. The use of CFD tools is now readily available and puts prediction of resistance and seakeeping within reach for most users.…”

SummaryPresent work describes a simple dynamical model for riverboat motion based on the square drag law. Air and water interactions with the boat are determined from aerodynamic coefficients. CFX simulations were performed with fully developed turbulent flow to determine boat aerodynamic coefficients for an arbitrary angle of attack for the air and water portions separately. The effect of wave resistance is negligible compared to other forces. Boat movement analysis considers only two-dimensional motion, therefore only six aerodynamics coefficients are required. The proposed model is solved and used to determine the critical environmental parameters (wind and current) under which river navigation can be conducted safely. Boat simulator was tested in a single area on the Ljubljanica river and estimated critical wind velocity.

“…catamaran [9] and trimarans [10]. It is possible to say that, accuracy of RANSE approaches on the estimation of resistance components is significantly improved over the last decades [11], on the other hand, there may be some problems to predict the wave profiles on the ship hull [12] and wave deformation in the far field [13].…”

SummaryIn this study, the computational results for KRISO Container Ship (KCS) are presented. CFD analyses are performed to simulate free surface flow around KCS by using RANS approach with success. Also the complicated turbulent flow zone behind the ship is well simulated. The RANS equations and the non-linear free surface boundary conditions are discretized by means of a finite volume scheme. The numerical methodology is found to be appropriate for simulating the turbulent flow around a ship in order to estimate ship total resistance and free surface. By the numerical results, total resistance is calculated for the ship model and the result is satisfactory with regard to the experimental one. As a result of well captured free surface, the wave elevation on/around the hull is compared with the experimental results.

“…Plenty of authors have published their papers in dealing with the determination of forces and moments (Vaz et al, 2010), the influence by using different turbulence closure models (Phillips et al, 2010;Sakthivel et al, 2011), the verification and validation of the results (Simonsen et al, 2003;Zhang, 2010), the comparison of dynamic characteristics of different geometries and configurations , and even the real simulation coupled with motions via overlapping grid techniques (Carrica et al, 2012) as well as the optimization process (Rajabi and Kavianpour, 2014). As recently reviewed by Stern et al (2013) and Stern et al (2014), CFD capabilities continue to advance at even faster speed, and are changing the face of shipbuilding industry by transforming the build-and-test design spiral approach to the simulation-based design (SBD) approach.…”

To estimate the maneuverability of a submarine at the early design stage, an accurate evaluation of the hydrodynamic coefficients is important. In a collaborative exercise, the authors performed calculations on the bare hull DRAPA SUBOFF submarine to investigate the capability of viscous-flow solvers to predict the forces and moments as well as flow field around the body. A typical simulation program was performed for both the steady drift tests and rotating arm tests. The same grid topology based on multi-block mesh strategy was used to discretize the computational domain. A procedure designated drift sweep was implemented to automatically increment the drift angle during the simulation of steady drift tests. The rotating coordinate system was adopted to perform the simulation of rotating arm tests. The Coriolis force and centrifugal force due to the computation in a rotating frame of reference were treated explicitly and added to momentum equations as source terms. Lastly, the computed forces and moment as a function of angles of drift in both conditions are compared with experimental results and literature values. They always show the correct trend. Flow field quantities including pressure coefficients and vorticity and axial velocity contours are also visualized to vividly describe the evolution of flow motions along the hull.
