Investigation of the use of Prandtl/Navier-Stokes Equation Procedures for Two-Dimensional Incompresslow around two dimensional bodies. We present computational evidence which shows that if the “obvious” coupling is used to combine the solutions, then the resulting solution is not accurate. We describe an alternate coupling procedure which greatly improves the accuracy of the solutions obtained wit

Vorticity Boundary Conditions for the Navier-Stokes Equation in Velocity-Vorticity Formulationthe vorticity function ω- velocity vector v formulation. The boundary conditions on the function ω (i.e the definition of ω as the curl of the velocity) are enforced by an influence matrix technique ., a fact that enables us to enforce everywhere in the domain the definition of the function ω as the

Numerical Simulation of Unsteady Flows Behind Cylindrical Structures Using a Finite Difference-Partins or flow-resonant sound interaction. In such problems there exists an obvious need for a stable, relatively accurate and easy to set up method to predict the complex unsteady vortex wakes and their effects on the structures. The method used here is based on the solution of the unsteady bidimension

Numerical Study of the Motion and Deformation of Two-Dimensional Bubbles by a Vortex Methodng the vortex blob method. To regularize the initial value problem for the vortex sheet a parameter .. was introduced in the Biot-Savart formula. We point out the viscous character of the δ. regularization. The evolution of circular and elliptical bubbles was studied. The numerical experiments showe

A Hybrid Vortex Method with Deterministic Diffusiony true because: (1) the Lagrangian solution of the Navier-Stokes equations eliminates the need to discretize the non-linear inertia terms, leading to good numerical stability at high ., and (2) the restriction of computational elements to the regions of the flow exhibiting shear and finite vorticity
