A Slightly Diffusive Contour Dynamicsution, where the jumps between contigous levels are expressed as functions of time. From an integral form of the Helmholtz equation the time derivative of these functions are defined by writing the balances for each region of constant vorticity via a suitable approximation of the exchanged vorticity

Vorticity Boundary Conditions for the Navier-Stokes Equation in Velocity-Vorticity Formulationtinuity equation are shown to be satisfied within machine accuracy and round-off errors of library routines. In the later case the computational domain is not simply connected, a fact that implies that an additionnal condition has to be imposed.

Moment Accelerated Contour Surgery explore essentially inviscid turbulence, and preliminary results show striking differences from those obtained using conventional (pseudo-spectral) methods. The differences can be attributed to an unexpectedly rapid, numerically-driven vortex erosion process operating in conventional methods.

A Coupled Potential-Boundary Layer Calculation Method for Unsteady Flows Around Airfoilssuch as friction coefficient or velocities inside the boundary-layer. The application fields of such model may be very large, since many mechanical modern devices are concerned by this kind of problems : rudders and keels of boats or submarine crafts, wings of manoeuvring planes, helicopter rotor blades, etc …
