Classical semi-implicit backward Euler/Adams-Bashforth time discretizations of the Navier-Stokes equations induce, for high-Reynolds number flows, severe restrictions on the time step. Such restrictions can be relaxed by using semi-Lagrangian schemes essentially based on splitting the full problem i
In this paper we develop and test an exponentially fitted finite volume method for the numerical solution of the Navier-Stokes equations describing \(2 D\) incompressible flows. The method is based on an Imsttuctured Delatmay mesh and its dhal Dischlet tessollation, comlined with a locally constant
A full spectral model for the stream-function-vorticity formulation is developed for the solution of unsteady flow past a rigid sphere. To convert the governing partial differential equations to discrete form, Chebyshev and Legendre polynomials are employed to expand the vorticity and stream functio
