A NUMERICAL INVESTIGATION OF THE REYNOLDS SCALE EFFECT ON THE RESISTANCE OF BODIES OF REVOLUTION

A numerical study of the resistance of bodies of revolution is performed by a systematic series of computer runs. The k - epsilon model is employed to calculate Reynolds stresses in a finite-volume method using a staggered grid. A new velocity-pressure coupling procedure as well as a grid refinement technique have been developed to accelerate convergence. The effect of various parameters affecting the numerical solution is investigated, such as external boundary conditions, wall function method und grid resolution. Applications of the method for two bodies of revolution show the trends of resistance components with Reynolds number, and comparisons are made with model-ship extrapolation approaches.
