NUMERICAL SOLUTION OF THE NAVIER-STOKES EQUATIONS FOR 2D HYDROFOILS

This report presents the results of an investigation of the application of numerically-generated boundary-fitted curvilinear coordinate systems in the finite-difference solution of the time-dependent, two-dimensional Navier-Stokes equations for the laminar viscous flow about hydrofoils moving either submerged at a finite depth or in a free surface of a fluid of infinite depth. The hydrofoil may be of arbitrary shape, and its motion may include pitching oscillation or oscillation normal or parallel to the plane of the undisturbed free surface as well as translation parallel to this plane. A computer code has been developed that is capable of predicting the flow field, pressure distributions, and force coefficients for this configuration at low Reynolds numbers. The finite-difference solution is implicit in time so that all the difference equations are solved simultaneously by iteration at each time step. (Author)
