CALCULATION OF STERN FLOWS BY A TIME-MARCHING SOLUTION OF THE PARTIALLY-PARABOLIC EQUATIONS. Conference Paper uri icon

abstract

  • The major features of a general numerical method for the calculation of the flow over the stern and in the wake of a three-dimensional body are described. The method is based on the solution of the partially-parabolic equations for a turbulent flow in curvilinear, nonorthogonal, numerically-generated, body-fitted coordinates using the novel 'finite-analytic' numerical scheme. It is shown that the entire zone of viscous-inviscid interaction can be captured, thus avoiding separate viscous-flow and potential-flow calculations and iterative matching, by using a large enough solution domain and coordinate stretching. The generality and flexibility of the method are demonstrated by applications to two-dimensional, axisymmetric and three-dimensional bodies.
