A method for computing turbulent flows around ship hulls is presented. The Reynolds-averaged Navier-Stokes equations are discretized by a finite-volume method. Either a Low-Re-Turbulence model or a standard #kappa#-#epsilon# turbulence model with wall functions is used. A nonlinear extension to the eddy viscosity hypothesis is employed. Flows aroun...
Improvements in computing the turbulent flow around ships Final report / Verbesserung der Berechnung turbulenter Schiffs...
The project aimed to improve the abilities of ship yards and consultants like, e.g., towing tanks in computing the flow around ships in steady ahead motion. Within a few years or even now, model experiments which are not accompanied by calculations will be estimated as unsufficient for developing effective ship hull shapes: The prediction quality a...
Calculation of the turbulent flow around ships with regard to the viscosity and turbulence Final report / Schiffsumstroe...
At present the turbulent flow around ships can be determined only for model Reynolds numbers of about 10 except when using wall functions; however, the latter leads to dubious results. The present research program aimed to develop a new procedure for such calculations avoiding wall functions. A finite-volume method using boddy-fitted coordinates as...
