A new finite-difference method is presented to solve the unsteady two-dimensional Navier-Stokes equations in the vorticity stream function form and tested for the flow around a cylinder at Reynolds number Re of IO?-104. The simulation uses a body-fitting Cartesian coordinate system in the physical p

A Lagrangian method that combines vortices and impulse elements (vortex dipoles) is introduced. The applications addressed are flows induced by the motion of thin flexible boundaries immersed in a two-dimensional incompressible fluid. The impulse elements are attached to the boundaries and are used
A numerical method is constructed for two-dimensional Navier-Stokes ows in a circular domain. Adaptive computational grids are employed to resolve the boundary layer and the boundary vorticity values are obtained in high order of accuracy. Numerical results show a quite good agreement with the asymp
We consider the lattice Boltzmann method for immiscible multiphase flow simulations. Classical lattice Boltzmann methods for this problem, e.g. the colour gradient method or the free energy approach, can only be applied when density and viscosity ratios are small. Moreover, they use additional field
