abstract = {<p style="text-align: justify;">Our aim in this article is to improve the understanding of the colocated finite
volume schemes for the incompressible Navier-Stokes equations. When all the variables are colocated, that means here when the velocities and the pressure are computed
at the same place (at the centers of the control volumes), these unknowns must be properly coupled. Consequently, the choice of the time discretization and the method used
to interpolate the fluxes at the edges of the control volumes are essentials. In the first
and second parts of this article, two different time discretization schemes are considered with a colocated space discretization and we explain how the unknowns can be
correctly coupled. Numerical simulations are presented in the last part of the article.
This paper is not a comparison between staggered grid schemes and colocated schemes
(for this, see, e.g., [15, 22]). We plan, in the future, to use a colocated space discretization and the multilevel method of [4] initially applied to the two dimensional Burgers
problem, in order to solve the incompressible Navier-Stokes equations. One advantage
of colocated schemes is that all variables share the same location, hence, the possibility to use hierarchical space discretizations more easily when multilevel methods are
used. For this reason, we think that it is important to study this family of schemes.</p>},
