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.

650 GPM	Radial Process Intensifier	Axial Process Intensifier
Lightnin
	ΔP = 19305 Pa = 2.8 psig	ΔP = 1034 Pa = 0.15 psig
Hayward Gordon
	ΔP = 26890 Pa = 3.9 psig	ΔP = 2758 Pa = 0.4 psig
