Some of the important results are the velocity vectors, contour of pressure coefficient, contours of pressure coefficient, contours of strain rate and contours of turbulence dissipation rate.
Figure 5: Velocity Vectors (Click on figure for original size)
Velocity vector plot shows the velocity of the fluids throughout the flocculator. As can be seen, there is a region of high velocity at the outer turn and recirculation at the inner turn. At the bottom of the flocculator, there is region of stagnant fluid.
Figure Figure 6: Contours of Stream Function (Click on figure for original size)
Contours of stream function tell us how the fluid travel in the flocculator. As can be seen from figure 6, there is enclosed streamline at the inner turn. The enclosed streamlines means there are recirculating fluid which are trapped in the region.
Figure 7: Contours of Pressure Coefficient
Figure 7 shows most of the pressure coefficient drop occurs around the bend. There is a pressure coefficient drop of about 3.7 across the bend. (Talk about the experimental result. Literature review data)
