We show that a non-physical velocity may appear in the numerical computation of the ยฏow of an incompressible ยฏuid subjected to external forces. A distorted mesh and the use of a numerical method which does not rigorously ensure the incompressibility condition turn out to be responsible for this phen

A spatial discretization of the incompressible Navier-Stokes equation is presented in which the velocity is decomposed using poloidal and toroidal scalars whose spatial dependence is given in terms of spherical harmonics and Chebychev polynomials.

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

A method of linearisation is described which enables the calculation of the steady state flow in networks of pipes and pumps handling an incompressible fluid. In an Appendix a numerical method is outlined for the repeated solution of large sparse sets of linear equations.
