“…Collocated meshes are known to generate spatially oscillating, checkerboard-like pressure fields, which can be eliminated through the so-called momentum interpolation, due to Rhie and Chow [23], by which continuity is no longer satisfied in its discretized form, but only in the limit of refinement, according to the order of the scheme. Despite the oscillating pressure field or, alternatively, the nonconservation of mass in the discrete sense, studies [4,[24][25][26][27] indicate that the accuracy of the velocity field, the stability, and the convergence characteristics of the cell-center collocated meshes are comparable to those of the staggered mesh.…”

“…A similar expression can be obtained for the north face velocity 6 n =Q n (6)+6 n −Q n (6 ). (20) The proposed interpolation is more appropriate when used in combination with the QUICK differencing scheme, where the convected cell-face velocities are approximated to third-order by formulae (16) and (17), setting =u or 6. The Rhie and Chow momentum interpolation of the convecting cell-face velocities is of only second-order (the order of linear interpolation, see Miller and Schmidt [11]).…”

“…These values are needed for the evaluation of the correction part of cell-face velocities according to the above interpolation practice, and also for the calculation of the pressure gradient source term in the momentum equations. The interpolation equations used are (16) and (17), where = P.…”

“…The symmetry and uniform distribution of the grid is suppose to amplify any problems that may be associated with the non-staggered methodology. For example, this problem and the similar problem of buoyancy-driven recirculation in a square cavity has been studied in a number of papers which test a non-staggered methodology, refer to, for example, References [25,26,32,45,46]. In this investigation various grid systems are employed consisting of 20× 20, 40× 40, 60×60 and 100×100 grid points.…”
