This is a continuation of the
Process Intensifier - Optimization with CFD: Part 1 paper.
Unlike the pictures used to determine the pressure drop, these pictures are to show the pressure distribution and the relative comparison of pressure drop between the units. The scale is the same for each device. Red = 45,000 Pa (6.5 psig) is the highest pressure and blue = -2500 PA (-0.36 psig) is the lowest pressure (behind the blades: this was lost in Figure 8 because it was colored blue, just like the outlet). Bluish-green is in each case = 0, meaning that this shows pressure above the outlet pressure (gauge pressure). The numbers are in Pascals. The pressure drop is harder to determine using this representation, but it is very easy to see which units have the larges pressure drops.
