Help Center Find new research papers in: The graphs include computed u-velocity along the vertical center line and v- velocity along the horizontal center line [7]. Peric, M. Pletcher, R. Thus, the momentum equation is rewritten in the following discrete form. This is because the cell center values of pressure and velocity were cancelled out on expanding the face gradient terms. Neighbors for Ue momentum control volume 4.

Neighbors for Ue momentum control volume 4. Several grid sizes have been studied and for different Reynold numbers , The graphs include computed u-velocity along the vertical center line and v- velocity along the horizontal center line [7].

Here the plots show results of the finest meshes ie.

In addition, the stream lines have been plotted for each Re value and were compared to the stream lines. Apart from a primary vortex, the formation of secondary vortices can be seen on the corners of the domain. Figure 4. In addition, for higher Re values, the primary vortex shifts more towards the center of the domain.

The results for other Re can also be seen below. For higher Re values, the primary vortex shifts more to the center and more corner secondary vortices are formed. The secondary vortices are also convected towards the center of the domain for higher Re values. Also with the convection of secondary vortices, more vortices are formed at the corners. Figure 6.

Figures 8, 9 and 10 show the stream line contours in the reference paper. Figure 8. In order from left to right: There is a good match of the computed results with the reference values.

Fine details like the corner vortices were also accurately predicted using fine grids. Generally, since the pressure-correction equation produces reasonable velocity fields, and the pressure equation works out the direct consequence without approximation of a given velocity field, convergence to the final solution should be much faster.

If the given velocity field happens to be the correct velocity field, then the pressure equation in SIMPLER will produce the correct pressure field, and there will be no need for any further iterations [13]. If on the other hand, the same correct velocity field and a guessed pressure field were used to initiate the SIMPLE procedure, the situation would actually deteriorate at first.

The use of the guessed pressure would lead to starred velocities that would differ from the given correct velocities. Convergence would take several iterations, despite the fact that we did have the correct velocity field initially [1]. However, since SIMPLER requires lesser iterations for convergence, the additional effort per iteration is more than compensated by the overall saving of effort [1].
