Power characteristic for laboratory vessel

Geometric parameters of the laboratory reactor were made dimensionless as required by the correlation equations. Table B.1 summarizes the values of the dimensionless parameters used. The equivalent blade height was estimated as

$$b_{eq}=\frac{n_p}{2.} b$$ (24)

since each impeller blade is equivalent to 0.5 paddle.

$\frac{b_{eq}}{D}$	$\frac{d}{D}$	$\frac{H}{D}$	$\frac{B_w}{D}$
$0.102$	$0.584$	$1.33$	$0.081$

Table B.2 gathers calculated parameters for the laboratory vessel.

Figure B.1 shows:

1. the ``no baffle'' curve
   

   $$N_e=\frac{A}{Re}+B \left(\frac{10^3+0.6 \cdot f \cdot Re^\alpha} {10^3+1.6 \cdot f \cdot Re^\alpha} \right)^p$$ (25)

   
   

2. the ``one baffle'' curve
   

   $$N_e=\frac{A}{Re}+B \cdot C \cdot \frac{N_{e,B}}{N_{e,\inf... ...cdot Re^\alpha} {10^3+1.6 \cdot f \cdot Re^\alpha} \right)^p$$ (26)

   
   

3. the ``fully baffled'' curve
   

   $$N_e=\frac{A}{Re}+B \cdot \frac{N_{e,max}}{N_{e,\infty}} \... ...cdot Re^\alpha} {10^3+1.6 \cdot f \cdot Re^\alpha} \right)^p$$ (27)

Laboratory vessel and CE12500 are geometrically similar (value of dimensionless parameters is close for the two configurations). Results of experiments and CFD simulations were compared to the ``1 baffle'' curve.
