GIGOLA, C. E.; NARDINI, M. L.; OLIVERA, A. C.  and  BRIGNOLE, N. B.. A Laboratory experiment for undergraduate instruction: non deal flow in tubular vessels. Lat. Am. appl. res. [online]. 2010, vol.40, n.4, pp.317-322. ISSN 0327-0793.

A laboratory experiment to reinforce the basic concepts of non-ideal flow is described. It consists of simple pulse-response measurements for gas that is flowing through an empty and a packed bed. It can provide information on the residence-time distribution function and other vessel parameters. Experimental results are compared with those predicted by the axial dispersed plug-flow model in order to obtain the Peclet number and the dispersion coefficient that characterize the flow behavior.

Keywords : Non-ideal Flow; Axial Dispersion; Residence Time.
