Bodenstein Number

Bodenstein number, abbreviated as Bo, a dimensionless number, is used in mass transfer and diffusion in reactors calculations in particular.

 

Bodenstein number formula
\(\large{ Bo = \frac{ v \; l }{ D_a } }\)
Symbol	English	Metric
\(\large{ Bo }\) = Bodenstein number	\(\large{dimensionless}\)
\(\large{ D_a }\) = effective axial diffusivity	\(\large{\frac{ft^2}{sec}}\)	\(\large{\frac{m^2}{s}}\)
\(\large{ l }\) = reaction length	\(\large{ft}\)	\(\large{m}\)
\(\large{ v }\) = velocity	\(\large{\frac{ft}{sec}}\)	\(\large{\frac{m}{s}}\)
