This is a continuation of the Process Intensifier - Optimization with CFD: Part 1 paper. Power per Unit VolumeA mixing quantity often needed for mass transfer studies (gas-liquid, liquid-liquid, and solid-liquid) and drop break-up mechanisms is power per unit volume. P/V of these units can be determined once the volume of the mixing chamber has been determined. The mixing volume of the radial Process Intensifiers is defined as the volume in the 10" (254 mm) pipe between the two Z-plate ends plus the volume of the T. This is 19.7" (500 mm) for LTR and 7.9" (200 mm) for HGR. For the axial designs, the active mixing volume (as can be seen on Figures 9-11) appears to be about 8" (203 mm) wide. The volume of the T is 0.42 Gallons (1.58 Liters).
Table 3 shows just how much specific power can be put into a mixing vessel. Because HGR has a shorter length between the Z-plate ends its P/V is extremely high. If this were attempted in a standard stirred tank, the contents of the tank would be flung right out of the tank. The motor and gearbox would also be much larger than the vessel. Notice also that HGA has about the same P/V as LTR using only 40% of the power of LTR. A mixer in a pipe is an excellent way for putting in high amounts of specific power effectively into a mixing vessel.
